Prepare the filling by mixing together the cream cheese, taco seasoning, and shredded cheddar cheese in a bowl.
Add the cooked ground beef or turkey to the cheese mixture and fold it in gently.
Spread about 1/3 of the filling onto each tortilla, leaving a small border around the edges.
Sprinkle diced tomatoes, jalapeƱos, and green onions over the filling on each tortilla, pressing them down slightly.
Carefully roll the tortilla tightly from one end to the other and place seam-side down on a cutting board.
Using a sharp knife, slice the rolled tortillas into 1-inch pieces and arrange them on a serving platter.
Optionally, refrigerate the roll-ups for about 30 minutes before serving, allowing flavors to meld and making them easier to handle.
