Frozen Edamame Is Less Than $3
For an easy-to-make, high-protein snack, buy frozen edamame. A 12-ounce pack costs between $1.50 and $3.00, depending on the store. Boil them, steam them, microwave them, or pan-sear them, and you’ll have a protein-filled snack or side dish.
But edamame is not only low in protein. It also has omega-3 fatty acids, vitamin C, and iron. According to the New England Journal of Medicine, soy products lower harmful LDL cholesterol and raise healthy HDL cholesterol. All of this comes from a $1.50 bag of edamame.
