Frozen peas

Think fresh is always best? Think again. When any type of produce is picked, it immediately starts losing nutritional value. Peas are particularly finicky and lose their nutrients a lot faster than sturdier vegetables. In fact, one study indicated peas any older than three days could be less nutritious than frozen ones.

A quick glance at the label on the package shows this freezer-aisle staple is a really smart choice. Calorie Count reported a ½-cup serving of frozen peas will set you back 62 calories and give you a decent amount of vitamins A and C, 4.4 grams of fiber, and an impressive 4.1 grams of protein. Pea protein is quickly becoming one of the go-to ingredients for nutrition bars, but you may as well save your money and get the real thing.

Like many of the other vegetables on this list, frozen peas are easy to add to just about any meal. Toss a handful into your favorite soups and rice dishes or serve them with just a dab of butter and a little bit of mint. Check outSerious Eats for more recipe inspiration.
