These easy roasted veggie tostadas are loaded with vegetables like corn, bell peppers, and onions, and make a tasty meatless weeknight meal! Top with your favorite salsa, sour cream, or avocado sauce.
Preheat the oven to 400ºF. Arrange onion, bell peppers, mushrooms, and corn in a single layer across one or two baking sheets. Sprinkle with salt and pepper to taste and toss with 1 tablespoon olive oil. Roast in the oven until the veggies begin to brown and caramelize, stirring two or three times, about 30 minutes.
When the vegetables come out of the oven, arrange the corn tortillas in a single layer on a baking sheet (working in batches as necessary) and lightly spray or brush both sides with olive oil. Bake the tortillas until crisp and just beginning to brown, 10-15 minutes.
While the tortillas are cooking, toss the roasted vegetables with the black beans and adjust seasonings as necessary. When the tortillas are done, top with the vegetable mixture. Finish with a tablespoon of cheese, avocado, tomatoes, microgreens, cilantro, a squeeze of lime juice, and a drizzle of poblano cream sauce if desired.

Drizzle with green avocado sauce, chipotle enchilada sauce, or top with healthy guacamole
Leave off the cheese and poblano cream sauce to make these vegan veggie tostadas
Use whatever vegetables you have on hand such as cauliflower or zucchini, adjusting the cooking time as needed
Swap the Monterey jack cheese for crumbled queso fresco
