Construct your snack stadium base by arranging the 14 cardboard magazine holders in a rectangular shape and secure them together side-by-side with duct tape to form tiers.
Layer sandwich stacks inside the stadium: On a clean surface, build stacks of bread, alternating with slices of ham and Cheddar cheese, to create mini sandwiches. Secure with toothpicks as needed.
Place sandwich stacks neatly inside the stadium tiers, pressing gently to fit.
In small serving bowls, mix 1 tablespoon chile-garlic sauce with 1 tablespoon sour cream for a spicy dip.
Place the tomatillo salsa, salsa con queso (reserving some for garnish), spicy sour cream dip, hummus, and red pepper hummus in various compartments around the stadium for dipping.
Arrange fresh baby carrots and broccoli florets around the stadium edges and in empty spaces for color and crunch.
Next to the veggies, arrange cheese-flavored crackers, pita chips, buttery round crackers, blue corn tortilla chips, ridged potato chips, nacho cheese-flavored tortilla chips, and crunchy cheese puffs in colorful groupings for variety.
Slice pepperoni beef sticks into bite-size pieces and skewer them on 10-inch skewers alongside cubes of Cheddar cheese (cut from the 2 pounds cheese) for easy grab-and-eat treats. Position these skewers standing upright in the stadium.
Drizzle remaining salsa con queso over some sandwich stacks or use it as an extra dip on the side.
Make sure all items are easy to reach and refill as needed during your event. Serve chilled or at room temperature for a spectacular snack stadium everyone will love!
