Chopped Taco Salad With Shrimp

This citrusy mix packs a ton of flavor and very few carbs. The colorful combination is surprisingly low-calories!

Ingredients:
Cooking spray
2 lemons, thinly sliced
2 limes, thinly sliced
3 tablespoons chopped fresh oregano
3 tablespoons extra-virgin olive oil
1/4 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
8 ounces romaine lettuce, chopped
20 large shrimp, peeled and deveined (about 1 pound)
4 (6-inch) corn tortillas
1 large ripe tomato, diced
1 diced peeled avocado
1 ounce Cotija cheese

Preparation:
Heat a grill or grill pan to medium-high heat; coat lightly with cooking spray. Quickly grill the citrus slices in batches, just until browned (about 1 minute per side); transfer to a cutting board, and finely chop. Transfer citrus to a medium bowl with any collected juices. Add the oregano, olive oil, salt, and pepper; mash with the back of a spoon to combine. Divide dressing in half.
Arrange lettuce on a serving platter; lightly coat the grill again. Grill the shrimp, in batches, until opaque, brushing with half of the lemon-lime dressing (about 2 minutes per side); transfer to the platter. Warm the tortillas on the grill until slightly charred (about 1 minute per side), brushing lightly with some of the remaining dressing; transfer to the platter.
Stir diced tomato into remaining lemon-lime dressing. Arrange avocado on the platter. Crumble the cheese over the salad; drizzle with remaining dressing.
