Step 1

Heat oven to 450°F. In a food processor, puree salsa and cilantro until smooth. Add sour cream and pulse to combine. Spread 1 cup mixture in 7- by 11-inch baking dish. Transfer remaining mixture to medium bowl.

Step 2

Heat oil in large skillet on medium-high. Add zucchini and cook 2 minutes. Add shrimp, then season with coriander, chili powder and 1/2 teaspoon salt and cook, tossing, 1 minute. Add garlic and cook, tossing, 1 minute. Remove from heat and toss with corn and cotija (shrimp shouldn’t be fully cooked).

Step 3

Wrap tortillas in double layer of damp paper towels; microwave on High until soft, about 1 minute (be careful of steam when removing). Working with 1 tortilla at a time, dip in reserved salsa mixture, shaking off any excess. Place on cutting board, top with heaping 1/4 cup filling, roll up and place, seam side down, in baking dish. Repeat with remaining tortillas and filling.

Step 4

Spoon any remaining salsa mixture on top. Sprinkle with Monterey Jack and bake until cheese begins to brown, 8 to 10 minutes. Serve topped with onion, cilantro, radishes and jalapeño.
