If you love pineapple on your pizza, you are going to love this sweet heat grilled cheese sandwich. Never thought of putting pineapple in your grilled cheese sandwich? Maybe you just needed someone to put the idea in your head, and we are happy to oblige. The sweetness of the pineapple could be overwhelming if not for the spicy jalapeño peppers that play off of it in the most delightful way.
Of course, grilling the pineapple is not completely necessary; you'll still get a scrumptious ooey-gooey cheese sandwich with a crunch that you wouldn't get from any ordinary grilled cheese sandwich. If you opt for that extra step, however, grilling gives the fruit a smoky flavor that works perfectly with both the mozzarella cheese and the jalapeño.
