Edamame is one of the best plant-based sources of protein—keep that in mind for a second: Explore Cuisine makes gluten-free pasta alternatives (think chickpea, lentil, black bean…). But its best—and most popular product—however, is its Edamame Spaghetti., which is loaded with plant-based protein (24 grams per serving), fiber, and iron and made from just one ingredient, 100 percent organic edamame.
