Preheat oven to 375.
Place slices of cheese on parchment lined baking sheet with few inches in between slices.
Bake for another 5 minutes or until bubble and just starting to brown at edges.
Remove baking sheet and let cool a couple of minutes.
Carefully pick up slices and place in muffin tin to form a cup shape. Let cool additional 10 minutes.
Salsa:
Place roma tomatoes, onions, jalapeno, lime juice and cilantro in medium covered bowl in fridge for at least 30 minutes or serve immediately - it gets more flavorful the longer it is in the fridge
Assemble cups by filling with preferred fillings and enjoy
