These individual ham and cheddar quiches are a snap to fix and bake in a muffin tin. Refrigerated crescent roll dough makes up the unbelievably easy crust. Consider these tasty, nutritious treats for a holiday morning or quick breakfast for kids to grab and run with on their way to school. Serve the quiches with juice and slices of cantaloupe or honeydew melon, whole strawberries, and seedless grapes for an elegant breakfast or brunch. Or add sliced tomatoes to the plate with the quiches. Allow two small quiches per person or one for small children. They are great for lunch, too. Serve the quiches along with some salsa or ketchup along with a tossed salad or cup of soup for a satisfying midday meal. The quiches are very adaptable, as well. Feel free to use swiss cheese or a cheddar jack blend instead of cheddar cheese. Or add about 1/2 teaspoon of finely chopped red onion or scallions to the ham. Bacon makes a tasty filling, too, or brown about 4 ounces of breakfast sausage; drain it well and add it to the filling mixture. For tex-mex flavor, use browned crumbled ground beef instead of ham, pepper jack cheese in place of the cheddar, replace the parsley with cilantro, add a bit of finely chopped red onion. Top them off with pickled jalapeo pepper rings if you'd like. If you have vegetarian (lacto-ovo) family members, just omit the ham and add some chopped steamed broccoli or chopped sauteed mushrooms to the filling.
