Caramelized shallots and sauteed lettuce enhance the sweetness of fresh peas in this warm spring salad.
Heat oil in a large skillet over medium. Add shallots and cook, stirring occasionally, until caramelized and tender, about 6 minutes. Add peas and 1 tablespoon water. Cook, stirring, until peas are tender and bright green, 4 to 6 minutes. Add butter and lettuce; cook, stirring, until lettuce is just wilted, about 1 minute. Season with salt and pepper; serve immediately.
