Cheese and fruit pair well, hence the popularity of sandwiches that use Brie and apples. This grilled cheese sandwich uses those same flavors but has a fun twist — the apples are replaced with GoGo squeeZ applesauce.
Start by melting one tablespoon of butter in a frying pan. Add the onions and mushrooms and sauté until golden brown.
Spread other tablespoon of butter on the outside of both slices of bread. Layer the cheese, onion, mushroom mixture, and applesauce on one piece of bread before closing the sandwich.
Heat a frying pan, then place the sandwich in the pan to cook, flipping it once after the cheese has started to melt and the bread is brown. The sandwich is done cooking when both sides are browned and the cheese is fully melted.
