4 Toma tomatoes
1 large garlic clove, minced
2 large jalapeno chiles, halved, seeded, and sliced, divided
1/2 c. fresh cilantro leaves, divided
3 T. fresh lime juice
Kosher salt and freshly ground pepper
1 t. olive oil
1/2 c. chopped onion
8 oz. shelled cooked crab
8 taco shells or soft tortillas
1 c. Iceberg lettuce, thinly sliced
1 c. shredded Jack or Cheddar cheese
1 avocado, thinly sliced
1/4 c. chopped green onion
Preheat oven to 350 degrees F. Put tomatoes, garlic, half of the jalapeno, 1/4 c. cilantro, and the lime juice in a food processor and pulse a few times to chop. Add salt and pepper to taste. Set salsa aside.
In a large skillet, heat oil over medium heat. Saute onion and remaining jalapeno until soft, 4 minutes. Add crab and cook just until crab is warm, about 2 minutes.
Put taco shells or tortillas on a baking pan and warm in oven, about 3 minutes. Arrange on a platter and fill with crab mixture, dividing evenly. Top crab with lettuce, cheese, and avocado. Sprinkle tacos with green onion and remaining 1/4 c. cilantro. Serve immediately, with salsa on the side or on top.
