To make homemade tostada shells: Preheat oven to 400 degrees F and line large baking sheet with parchment paper or silicone mat. Arrange tortillas in a single layer, spray with cooking spray and sprinkle with salt on both sides.
Bake for 6 minutes per each side, means you have to flip one time.
Prep toppings: While tostadas are baking, make easy guacamole salsa by combining tomato, avocado, red onion, cilantro, cumin, chili powder, salt and lime juice. Get other ingredients ready.
Assembly: To assemble tostadas, top each shell with guacamole salsa, beans, chicken and cheese.

Notes
Store: You can bake homemade tostada shells for up to 48 hours in advance. Just store in resealable Ziploc bag to keep shells crunchy.
Make ahead: You can shred chicken, chop/dice veggies, crumble cheese for up to 48 hours in advance and store in airtight containers. Prep guacamole up to 24 hours in advance.
Why make homemade tostada shells? Store-bought tostadas shells are full of artificial colours and preservatives. I prefer to make my own tostada shells (not corn tortillas) but you can use pre-made.
100% corn tortillas: Also, use thinner ones vs. thicker ones for the crispiest baked tostadas.
Healthy brand of refried beans instead of black beans is welcome. Low in sodium, with less ingredients and possibly organic. Alternately, use low sodium pinto beans.
Adjust sodium based on ingredients: Adjust salt in guacamole to taste depending on whether you use store-bought tostada shells, salted canned beans and store-bought or homemade chicken.
Cheese: Substitute for cheddar, cheddar Jack or your favorite. Just remember freshly grated for best taste!
