Spinach, avocado, goat cheese grilled cheese: 2 out of 5 stars. I didn't have spinach so it was just avocado and goat's cheese. The avocado was mushy when warm. I prefer other combinations of grilled cheese.
A CUP OF JO: Grown-Up Grilled Cheese Sandwich - her recipe includes caramelized onions and kale. I've never tried kale, but I like the idea of caramelized onions. How does roast beef, American cheese, and caramelized onions sound?
