Wash and finely chop broccoli, red bell pepper, and carrots into small even bits. I like to mince them extra small so each bite has a taste of everything.
In a medium bowl, soften the cream cheese first. Stir in the mayonnaise, garlic powder, dried dill, salt, and pepper until smooth and uniform.
Microwave each tortilla for 15–20 seconds—they become more pliable and easier to roll without cracking.
Spread the cream cheese mixture evenly onto each tortilla. Sprinkle the chopped veggies, cheddar cheese, and green onion on top, distributing evenly.
Start from one edge and tightly roll the tortilla all the way through, pressing gently as you go. Use toothpicks if needed to hold in place. Chill in the freezer for 20 minutes to firm up (or refrigerate overnight if prepping ahead).
Once chilled firm, slice into ½-inch pinwheels and serve. The cream cheese helps hold everything together.
