Follow the steps in order for the best result.
Preheat your oven to 400 degrees Fahrenheit. Lightly grease or spray a 15x10 inch or larger dark or nonstick baking sheet.
Unroll the pizza dough onto the prepared baking sheet. Starting from the center, gently press the dough outwards to form a 15x10 inch rectangle.
In a small bowl, thoroughly combine the salsa and the finely chopped chipotle chile. Spread this mixture evenly over the pizza dough, leaving about 1/2 inch of space around the edges.
Distribute the chicken strips, chopped onion, and both the red and green bell peppers evenly over the salsa-covered crust.
Generously sprinkle the shredded Mexican blend cheese over all the toppings.
Bake in the preheated oven for approximately 10 to 12 minutes, or until the pizza crust turns a lovely golden brown and the cheese is completely melted and bubbly. Serve immediately and enjoy!
