Unlike chili peppers, bell peppers lack the fiery compound capsaicin, giving them a sweet, mild flavor and a satisfying crunch.

- Red Bell Peppers: These are fully ripened green peppers. They are the sweetest and most nutritious. Compared to green bell peppers, red ones have almost 11 times more beta-carotene and 1.5 times more Vitamin C.

How to Use and Prep Bell Peppers
Peppers are incredibly versatile. You can add them raw to everything from dips and salads to pasta dishes. They can be enjoyed raw, cooked, roasted, fried, or pickled.
