In a small bowl, stir together cream cheese, minced garlic, and taco seasoning until smooth and creamy.
Lay out your tortillas and evenly spread the cream cheese mixture over each one. Then, layer on the shredded chicken, cheddar cheese, drained Rotel, and green onions.
Starting from one end, tightly roll each tortilla into a log. Wrap them in plastic wrap and refrigerate for at least an hour. (This helps the pinwheels hold their shape when sliced.)
Once chilled, unwrap and use a large serrated knife to slice each roll into 6 one-inch pieces.
