Look for salty crumbly fresh Mexican cheese—queso fresco—near other fresh cheeses. Swap crumbled feta or shredded Jack cheese in a pinch. Look for crunchy premade tostada shells near the taco shells. Use up the extra shells as a base for a batch of after-school nachos, or break them into pieces and use in place of tortilla chips. For even more veggie goodness and an extra punch of flavor, try adding a few slices of creamy avocado and a sprinkle of charred corn kernels.
