In a food processor, pulse the tomatoes, the chilies and any sauce coating them, and ½ teaspoon salt until mostly smooth, 1 minute. Set aside.

In a 12-inch nonstick skillet over medium-high, heat 2 tablespoons of oil until beginning to smoke. Add half the shrimp and cook, stirring, until golden, about 45 seconds. Transfer to a bowl. Repeat with remaining shrimp, adding them to the bowl. Toss with 2 tablespoons of lime juice. Set aside.

Return the skillet to medium-high and add the remaining 2 tablespoons oil. Add the onion and cook for 3 to 4 minutes. Add the garlic and oregano and cook until just beginning to brown, 1 minute. Stir in the wine and any accumulated shrimp juice from the bowl. Cook until nearly evaporated. Add the chipotle mixture and simmer, stirring, until thick enough to coat a spoon, 10 to 12 minutes.

Remove the skillet from the heat. Stir in the shrimp, cover and let sit until the shrimp are opaque and cooked through, 2 to 4 minutes. Stir in the cilantro and remaining lime juice. Taste, then season with salt and pepper. Serve with warmed tortillas, avocado, sour cream and lime wedges.
