It really is the simple things that make the tastiest meals some times. Just top a tortilla with refried beans, some salsa, some corn kernels and some sliced up shaved ham. Add finely chopped cilatro, and a squeeze of lime juice.
Top liberally with mozzarella cheese, and another tortilla. Fry in a hot pan until underside is golden, and then quickly and carefully flip over to fry the other side. You'll spill cheese on the pan until you get the hang of this, so it would be best to use a non-stick pan. Cut into wedges and serve with salad.
