Mix softened cream cheese with the ranch powder, cheddar cheese, bell pepper and onion until well combined.
Spread about 2 Tbsp of this mixture evenly on each tortilla then lay 3-4 slices of turkey breast flat on top of the cheese mixture to cover in a single layer.
Roll the tortilla up gently, yet tightly to make sure it holds together and keeps its shape.
Use a serrated knife to gently slice the roll up into 5-6 slices.
Eat immediately, or refrigerate to firm up and serve later.
