Combine the cheese mixture in a mixing bowl. Use a hand mixer or spatula to blend the cream cheese and cheddar cheese for about 2-3 minutes until smooth.

Add all flavor components including onion, salsa, cumin, cayenne, garlic powder, salt, and pepper. Stir until vibrant in color and well mixed.

Shape the mixture into a ball. If too soft, refrigerate for 15-20 minutes to firm up.

Roll the ball in crushed tortilla chips to coat, creating a pumpkin-like texture.

Shape the cheese ball into ridges and insert the bell pepper stem to complete the pumpkin look.

Cover with plastic wrap and refrigerate for at least 1 hour to set.

Serve with an assortment of crackers or fresh vegetable sticks.
