Grilled Vegetable Tostadas

Think of these as open-faced Mexican sandwiches, topped with grilled summer vegetables, tangy feta cheese, and fresh tomato salsa.

Recipe information

  • Yield

    Serves 4

Ingredients

3 tablespoons olive oil, plus more for grates
3 medium zucchini (1 1/2 pounds total), cut into 1/2-inch-wide slices on the diagonal
4 portobello mushrooms (1 pound total), stemmed
1 1/2 bunches scallions, root ends trimmed
Coarse salt and fresh ground pepper
4 flour tortillas (10-inch or burrito-size)
3 cups Fresh Tomato Salsa (recipe below), or store-bought fresh salsa
4 ounces feta cheese, crumbled (1 cup)
1 lime, cut lengthwise into 4 wedges (optional), for serving

Fresh Tomato Salsa

1 1/2 pounds plum tomatoes (6 to 8), cored, halved, and seeded
1/2 medium red onion, minced (1/2 cup)
1 jalapeño or serrano chile (ribs and seeds removed for less heat, if desired), minced
1 small garlic clove, minced
1/2 cup chopped fresh cilantro
2 tablespoons fresh lime juice (from 1 lime)
Coarse salt

Preparation

  1. Step 1

    Heat the grill to high; lightly oil the grates. In separate piles, arrange the zucchini, mushrooms, and scallions on a baking sheet. Drizzle with 2 tablespoons of the oil; season with salt and pepper. Working in batches if necessary, remove each pile of vegetables from the baking sheet. Grill, turning once, until lightly browned and tender, 2 minutes for scallions, 6 minutes for mushrooms, and 8 minutes for zucchini. Return all the vegetables to the baking sheet. Slice the mushrooms into 1/2-inch-wide strips. Set aside.

    Step 2

    Brush the tortillas with the remaining tablespoon oil; grill, turning frequently, until browned and very crispy, about 2 minutes. Place 1 tortilla on each serving plate; cover evenly with mushrooms and zucchini. Using kitchen shears, snip scallions over the vegetables. Top with the salsa, and sprinkle with the feta; serve with lime wedges, if desired.

  2. Fresh Tomato Salsa

    Step 3

    Chop the tomatoes into 1/4-inch pieces; transfer to a medium bowl. Add the onion, chile, garlic, cilantro, and lime juice; season generously with salt. Mix to combine. Let stand 15 minutes to develop flavor. Salsa can be kept at room temperature up to 2 hours. To store, transfer to an airtight container, and refrigerate up to 3 days.
