Note: Spice it up. If you like more heat, use pepper Jack cheese instead of plain Monterey Jack.
Swap salsas. Don't care for mango or can't find one? Sub in tomato salsa instead.
Go green. To add another layer of flavor, sprinkle on some chopped avocado and fresh cilantro after assembling.
Put in more fruit. Mango gives the dish a touch of sweetness. Substitute or add chopped papaya, pineapple or kiwi for even more of a tropical taste.
Try another base. We used small flour tortillas for these tostadas, but you can use corn tortillas if you prefer.
