Begin by gathering and preparing all your ingredients. Shred the cooked chicken, chop the green onions, and dice the bell peppers.

In a mixing bowl, combine the shredded chicken, softened cream cheese, shredded cheese, chopped green onions, diced bell peppers, garlic powder, salt, and pepper. Mix until all ingredients are well combined.

Lay a tortilla flat on a cutting board. Spread an even layer of the chicken and cheese mixture over the tortilla, leaving a small border at the edges.

Starting at one edge, carefully roll the tortilla tightly into a log shape. Ensure that the filling stays inside as you roll.

Once rolled, use a sharp knife to slice the log into pinwheel shapes, about 1-inch thick.

Arrange the pinwheels on a platter and serve immediately, or refrigerate until ready to serve.
