One-dish meals are flavorful in & of themselves, but if you’d like to add more zip or zest to casseroles, skillets, soups or salads, try the following add-ins & toppings:
add plain or flavored feta cheese to a salad.
sprinkle shredded swiss cheese over individual servings of soup.
intensify the flavor of veggies by seasoning them with balsamic vinegar or soy sauce.
use a flavored pasta sauce instead of plain.
sprinkle canned french-fried onions over the top of casseroles.
add a dash of soy sauce to skillet & stir-fry dishes.
stir a tablespoon or two of pesto into a pot of soup.
substitute flavored mayo for plain in pasta salads.
