A little context: The USDA recommends that women between the ages of 19 and 30 on a 2,000 calorie-per-day diet eat 46 grams of protein a day, and for men of the same age, 56 grams protein per day. A table of exactly how much protein you need for your age and body can be found here.
Keep in mind that not all proteins are created equal. It will take a larger amount of leafy greens than, say, beans to make you feel full. But if you're looking for a few extra grams here or there along with the vitamins and nutrients that veggies provide, consider getting even more involved with the ones on this list!
1. Chickpeas
Protein per cup: 16 grams
Protein per ounce: 6 grams
Chickpeas are a great food that you can add to meals to keep you feeling full. If you don't like them as they are, try hummus — or put them in a a salad!
2. Kale
Protein per 2 cups raw kale: 1 gram
Kale. You love it, you hate it, but gosh darn it, kale is good for ya! Looking for a recipe? Try kale chips.
3. Quinoa
Protein per cup of cooked quinoa: 8.14 grams
Protein per ounce: 3 grams
Quinoa, in all of its colors, gives you 8 grams of protein per cup. Not bad! Start out with a quinoa bowl at lunchtime or this Southwestern quinoa salad at dinner. You can even make quinoa crackers!
5. Chia Seeds
Protein per cup dry: 38 grams
Protein per tablespoon: 2 grams
Ah, chia seeds. Did you know that the stuff you played with as a kid when you made your first Chia Pet is actually jam-packed with vitamins and minerals? Well, it is! Sprinkle them in your yogurt, salads, or test out chia seed oatmeal sometime for breakfast.
6. Hemp Seeds
Protein per tablespoon: 11 grams
Hemp seeds have a mild flavor, so they can be easily added to any salad, pestos, soups, and pretty much any savory dish — or your morning
7. Spinach
Protein per cup raw: ~1 gram
Protein per tablespoon: 1 gram
Ayye, this wasn't Popeye's favorite food for no reason! Use it in your salads to feel full longer, blend it in smoothies, juice it, or put it in virtually any meal.
8. Rice
Protein per cup of cooked white rice : 4 grams
Protein per cup of cooked brown rice: 5 grams
Is there a person in this world who doesn't like rice? I'd like to meet them. Because I'd tell them that they're missing out on so much: sushi, rice bowls, risotto, and so many other delicious foods across the world!
9. Avocado
Protein per cup, pureed: 4.6 grams
Protein per cup, cubed: 3 grams
Yes, avocado toast is a bit played out...but there's so much else to do with these guys! Bake them, fry them, make pudding, or use it as a replacement for butter and cream in your favorite recipes.
10. Lentils
Protein per cup cooked: 17 grams
Protein per cup raw: 47 grams
Protein per ounce: 7 grams
Just one cup of lentils will provide you with 37% of the USDA recommended protein intake, so you might as well start learning how to use them in soups, hummus, burgers, and to make your own dal! Try these lentil nuggets or lentil meatballs, too!
11. Tempeh
Protein per cup cooked: 30 grams
Protein per ounce: 5 grams
This fermented food is super filling, with 30 grams of protein per cup, and it's my personal favorite meat replacement. It's tasty! It makes a great vegan bacon, taco salad, and there's even a recipe for a General Tso's tempeh.
12. Split Peas
Protein per cup: 16 grams

Split peas — whether you go for green or yellow — pack a punch with a whopping 16 grams of protein per cup. Try them in a soup or add them to your mac & cheese!
13. Sesame Seeds
Protein per cup: 25 grams
Protein per tablespoon: 2 grams
NOT that you'd ever eat an entire cup of sesame seeds in one sitting, but that could totally happen with tahini or hummus, let's be honest. Sprinkle these guys on anything and everything and learn how to make your own tahini!
14. Cauliflower
Protein per cup raw: 2 grams
Yes, of course you can eat the regular white cauliflower, too. But why wouldn't you want to try the green fractal-y goodness that is the Romanesco cauliflower? Regardless of the style you choose, you've got a lot of options these days: steaks, fritters, wings, fried rice, tacos, soup, hash browns... eat them whole or, you know, just eat them plain.
15. Alternative Nondairy Milks
Protein per cup of soy milk: 4 grams
Protein per cup of almond milk: 5 grams

Enjoy them steamed and with salt, or mix it up with a new recipe!

These guys give a bonus of 4 grams of dietary fiber for each cup, and can be prepared in a variety of ways. Try them with almonds to start!
23. Almonds

Protein per tablespoon: 2 grams
Raw sunflower seeds have 2 grams of protein per tablespoon and are great to snack on, put in granolas, and make nut butter from.
26. Cucumbers
