Prepare the Cream Cheese Spread: In a small bowl, combine the softened cream cheese, mayonnaise (or Greek yogurt), Dijon mustard, garlic powder, onion powder, salt, and pepper. Mix until smooth and creamy. Adjust seasoning to taste.

1. Prepare the Fillings: Wash and chop the vegetables (lettuce, cucumber, and bell pepper). Lay out the tortillas on a flat surface.
2. Spread the Cream Cheese Mixture: Evenly spread a thin layer of the cream cheese mixture on each tortilla, covering the entire surface.
3. Layer the Fillings: Place a slice of deli meat in the center of each tortilla. Then, add shredded cheese, followed by a handful of chopped lettuce, cucumber, and bell pepper.
4. Roll the Tortillas: Carefully roll up each tortilla tightly, ensuring that the filling stays inside. Be gentle to prevent spilling. Roll from one edge to the other, keeping the roll tight.
5. Slice the Pinwheels: Using a sharp knife, slice each rolled tortilla into 1-inch thick pinwheels, making about 8-10 pinwheels per tortilla.
6. Serve: Arrange the pinwheels on a platter. Garnish with fresh herbs like parsley or dill if desired, and serve immediately or refrigerate until ready to serve.
