Step 1

The Goya seasoning can be found in the spice or international section of your grocery store; Lawry's Seasoned Salt is usually stocked with other salt blends in the spice section. You can wrap the sandwiches in butcher paper instead of parchment paper, if desired.

Step 2

Adjust oven rack to middle position and heat oven to 400 degrees. Combine beef, onion, all-purpose seasoning, and seasoned salt in 12-inch nonstick skillet. Cook over medium-high heat, constantly breaking up meat into small pieces with wooden spoon, until cooked through and excess moisture is driven off, about 8 minutes.

Step 3

Arrange sub rolls on baking sheet and spread mayonnaise and ketchup evenly on cut sides of rolls. Divide beef mixture evenly among rolls. Layer 2 slices American cheese over beef on each roll. Bake until bread is warmed through and cheese is melted, about 5 minutes.

Step 4

Layer tomatoes and lettuce over cheese. Close 1 sandwich, using spatula as needed to keep ingredients contained within roll (sandwich will be very full). Starting from corner of 16 by 12-inch sheet of parchment paper, immediately wrap sandwich tightly. Repeat closing and wrapping with remaining 3 sandwiches. To serve, cut sandwiches in half through parchment paper and unwrap as you eat.
