Step 1

Preheat oven to 375ºF. Line a baking sheet with parchment paper.

Step 2

Place yogurt and flour in a large bowl; stir well with a wooden spoon until just combined and then keep mixing dough in bowl with your hands until smooth (about 2 minutes of kneading). If dough is too sticky to knead, add more flour, 1 Tbsp at a time, until no longer sticky.

Step 3

Place a large piece of parchment paper on a work surface and sprinkle with a little flour; place dough on paper. Use a knife to cut dough into 4 equal pieces. Use a rolling pin to roll each piece of dough into a 6-inch circle; slightly curl up edges to make a crust with a center. Place on prepared baking sheet; bake until dough is cooked through, 18-22 minutes.

Step 4

Remove from oven. Stir together the beans and chili powder. Spread ¼ c beans on each tostada and top with 2 Tbsp corn, 2 Tbsp tomato and 1 Tbsp feta. Garnish with the cilantro. Serve with hot sauce, if desired.

Step 5

Serving size: 1 tostada
