Make these tostadas on the grill, in the summer, when produce is most flavorful and everyone will enjoy them to the fullest.


  • 3 tablespoons olive oil, plus more for grates

  • 3 medium zucchini (1 ½ pounds total), cut into ½-inch-wide slices on the diagonal

  • 4 portobello mushrooms (1 pound total), stemmed

  • 1 ½ bunches scallions, root ends trimmed

  • Coarse salt and ground pepper

  • 4 flour tortillas, (10-inch or burrito-size)

  • 3 cups store-bought fresh salsa, or Fresh Tomato Salsa

  • 4 ounces feta cheese, crumbled (1 cup)

  • 1 lime, cut lengthwise into 4 wedges (optional), for serving


  1. Heat grill to high; lightly oil grates. In separate piles, arrange zucchini, mushrooms, and scallions on a baking sheet. Drizzle with 2 tablespoons oil; season with salt and pepper. Working in batches if necessary, remove each pile of vegetables from 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 vegetables to baking sheet. Slice mushrooms into 1/2-inch-wide strips. Set aside.

  2. Brush tortillas with 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 vegetables. Top with salsa, and sprinkle with feta; serve with lime wedges, if desired.
