Heat oil in a large skillet over medium heat. Add ground turkey and cook until beginning to brown, 4 to 5 minutes. Sprinkle with taco seasoning. Cook and stir until turkey is no longer pink, 1 to 2 minutes.

Add 1 cup pico de gallo, broccoli slaw, and chopped bell peppers. Cook, stirring occasionally, until peppers begin to soften, about 2 minutes. Stir in diced tomatoes and tomato sauce; cook until simmering and heated through, about 5 minutes.

Divide tortilla chips evenly and layer onto 4 microwave-safe plates. Spoon turkey mixture on top, sprinkle with Cheddar cheese, and spray with cooking spray.

Microwave each plate on high until cheese has melted, about 1 minute. Serve with remaining pico de gallo.
