Everyone knows peas are good for you. Nobody eats them.
Peas have some of the best protein and fiber per calorie in the produce aisle. They lost on texture and flavor, not nutrition. That's a fixable problem.
Why they tasted bad
The peas you grew up with were boiled soft or fried under a starch coating. The "beany" flavor isn't the pea. It's an enzyme, and a quick blanch shuts it off. Heat fixes it. Additives don't need to.
Why roasting
Roasting gets a whole pea crunchy all the way through without a fryer. No starch shell, no seed-oil bath, no flavor dust. Just a pea with the texture of a snack.
Why the label is short
Four ingredients is the product. If it needed a fifth to taste good, we'd change the process, not the label.
