There must be a lot of seven-layer dip fans because these Seven-Layer Tostadas have been a hit with everyone who's tried them. This would be perfect for Cinco de Mayo, or any time you want a quick and easy vegetarian meal. I use low-carb tortillas that are crisped in the toaster oven, but if you don't care about that using pre-cooked corn tortillas for the base would make it even faster to get on the table.

These simple, vegetarian and gluten-free tostadas are topped with a spicy black bean puree and piled high with Mexican street corn flavored with sour cream, chili, lime, garlic, and plenty of feta and chopped fresh cilantro.
