Preheat oven to 375°F.
Rub chicken with olive oil and Cajun seasoning.
Heat 2 tbsp olive oil in a skillet over medium heat. Cook chicken about 5 minutes per side until cooked through. Set aside, then dice.
In the same pan over medium-low heat, melt butter and sauté onion and red pepper until softened, about 5–7 minutes.
Dip each tortilla in water until fully wet, then shake off excess water.
Slice tortillas in half horizontally.
Sprinkle about ¼ cup cheese down the center of each tortilla half.
Add 1/4 cup each of: diced chicken, peppers and onions, ranch, bacon, and another layer of cheese.
Fold corners inward to form triangles.
Arrange triangles in a pie pan like pizza slices.
Top with remaining cheese and parsley.
Bake until cheese is bubbly and tortillas are golden around the edges, about 20 minutes.
