Prepare the tostadas. Preheat the oven to 300 degrees. Lay the tostadas on a baking sheet in a single layer and place in the oven for 5 minutes to warm them up. See recipe notes if you need to make tostadas from scratch.
Warm up the refried beans. Empty the can of refried beans in a glass microwavable bowl and microwave for 1 minute and 30 seconds. If the refried beans are tasteless, add a squeeze of lime, and a pinch of cumin, chili, and salt.
Prepare the fixings. Chop the cilantro, tomatoes, jalapeño, and olives. Crumble the cheese. Place the tostada on a plate, slather on some refried beans, and top with all the prepapred fixings. Mangia!
