Grilled Peanut Butter and Banana Sandwich. Delish! I even dabbed part of mine in a smidge of chocolate syrup (making it a little dessert-y). It is exactly like you'd like a grilled cheese, but careful when the peanut butter starts getting melty as it can be messy. I buttered the grilled sides rather than the spray. But I imagine the cooking spray could be healthier and less hassle. But, yes, definitely worth a repeat!
