Planning to picnic this spring and summer? Bring Strawberry Romaine Salad in a Jar along as a tasty, seasonal side dish. Romaine lettuce is layered into a mason jar, followed by fresh, sliced strawberries. The lettuce and fruit are topped with toasted pecans and feta cheese, then tossed in a homemade lemon vinaigrette to complete the dish. These salads in a jar travel well, store well, and are easy to enjoy at any warm-weather outdoor event you might be attending!
