For a vegetarian version, simply omit the bacon and use a vegetarian-friendly cream of mushroom soup. You can also add sliced mushrooms or diced bell peppers for extra flavor and texture. If you prefer a spicier kick, try adding a pinch of cayenne pepper or some chopped jalapeños. For a lighter version, use low-fat milk and reduced-fat sour cream. This recipe is quite forgiving, so feel free to experiment with different cheeses or add some cooked chicken for a protein boost.
