I like grilled cheese made with mozzarella and a little bit of pesto.
I also like sautéed mushrooms and Swiss cheese in croissants, heat the foil wrapped stuffed croissants in the oven to melt the cheese.
I’ll have to try that. When I am overwhelmed with tomatoes from the garden I make tomato and grilled cheese sandwiches. Add mayo on the inside of your sandwhich, the cheese, tomato slices and a pinch of dried herbs (whatever you like) then make it like a regular grilled cheese.
