Bacon Tomato Grilled Cheese

8 slices sourdough bread
4 slices mozzarella cheese
2 large tomatoes, thinly sliced
8 bacon strips, cooked
4 T sour cream
4T finely chopped onion
1/4 t dried oregano
4 slices cheddar cheese
2 T butter, softened

For each sandwich, top one slice of bread with one slice of mozzarella cheese, a fourth of the tomato slices, two bacon strips, 1 T sour cream, 1T onion, a pinch of oregano, one slice of cheddar cheese and another slice of bread. Spread outside of sandwiches with butter. On a hot griddle over medium heat, grill sandwiches for 3-4 minutes on each side or until lightly toasted.

*I usually mix the sour cream, onion, and oregano in a bowl and just spread it on after the bacon. This recipe was found in a Taste of Home magazine some years ago.
