Baking sheet, cutting board, knife, skillet, medium bowl, spoon
Ingredients
4 small corn tortillas
2 colorful heirloom tomatoes, diced
2 cups fresh or frozen corn
1 cup refried beans
1/2 lime, juiced
Small bunch fresh cilantro, chopped
Pinch of ground cumin
Cooking spray or oil
Optional toppings: cotija cheese, chopped red onion, sliced jalapenos, salsa, extra cilantro
Directions
Preheat the oven to 415F. If using fresh corn, cut the kernels off the cob. Spread the corn on a baking sheet and roast in the oven for 15-20 minutes, stirring halfway, until lightly browned. Set aside.
Lightly spray both sides of the tortilla with oil. Place on a baking sheet and bake for 4 minutes. Flip and bake for another 5 minutes, or until crisp.
Heat the refried beans in a skillet over medium-low heat until warmed through.
In a bowl, combine the diced tomatoes, roasted corn, chopped cilantro, lime juice, and a pinch of cumin. Mix well.
To assemble the tostadas, spread a spoonful of refried beans on each baked tortilla. Top with the tomato-corn mixture and your favorite toppings.
