I wanted to do something with the collard greens I just bought at the store. One of the best recipes I ever created using these greens had a bit of brown sugar, black eyed peas and sliced lean ham and was for a project creating healthier African-American recipes. But I was out of the latter two items so had to think of something new. Apples, onions and walnuts came to mind and they were on hand.This warm salad was very easy to make. Start with a large pan over medium-high heat and add a little olive oil. Saute sliced onion (1), apples (2) and walnuts until golden brown, about 3-4 minutes, stirring often. Add the frozen chopped collard greens (1 bag) and cover and cook until tender, about another 8 minutes over low heat. Season with fresh lemon juice and fresh ground pepper and serve warm.This warm salad went with lasagna - dinner was ready in 15 minutes. (Lasagna was defrosted and reheated from another night.)
