Pan-Seared Tuna Tacos with Avocado and Mango Salsa

These simple, colorful tacos are based on mostly super-sweet ingredients to maximize their flavor potential. Choose fresh-ripened avocados and tuna from a source you trust.
Preheat a medium skillet over high heat. Pour the oil into the pan; stir to coat. Dry the tuna with a paper towel. Sprinkle the tuna with salt and pepper. Transfer the tuna to the skillet; cook for 2 minutes on each side or until desired browning. Transfer the tuna to a cutting board; cut across the fibers in 1/4-inch thick slices.Preheat the tortillas according to the instructions on the package. Spread the tuna evenly over the tortillas. Sprinkle each taco with 1 tablespoon of salsa, 1 1/2 teaspoons of sour cream, and 2 slices of avocado. Serve immediately.
