Set up designated serving stations: a hot dog and burger bar, a cold sandwich and snack area, a drink station, and a dessert table.
Preheat your grill to medium-high heat and your oven to the temperature specified on the French fry package.
Bake the frozen French fries in the oven for 20-25 minutes until golden and crispy.
Grill the beef hot dogs for 5-7 minutes, turning frequently until slightly charred. Grill the beef burger patties for 4-5 minutes per side until fully cooked, adding cheddar cheese slices during the last minute of cooking.
While meats are grilling, pop the popcorn kernels using a stovetop popper or air popper. Transfer to a large serving bowl alongside the potato chips.
Assemble sub sandwiches by layering beef deli meat and fresh lettuce into the sub sandwich bread loaves, then slice into smaller portions.
Pour lemonade and red fruit punch into large drink dispensers with ice.
Arrange the baseball-themed cupcakes, rice crispy treats, and chocolate brownies on a large platter. Serve alongside scoops of vanilla ice cream just before dessert time.
