What each ingredient does

Lean bacon: Adds savory, salty flavor and fat that seasons the peas as it renders.
Green peas: Form the main body of the dish, providing sweetness and a tender texture when cooked.
Boiling broth: Moistens the peas and carries flavor while the dish simmers.
Lettuce: Wilts when braised, adding soft texture and a mild, sweet vegetable flavor.
