Form your plant based meat into 4 oz patties and add to a hot griddle. Each sandwich should have 8 oz. worth of meat, or use less if you like as well. Add in a few handfuls of onions for each sandwich (about 1 cup worth) and season to taste with the adobo and or sazon seasoning.
After 2-3 minutes, flip your patties, and grill for another 3 minutes or so.
Chop up your patty as fine as you like and combine the meat and onions together. Cook for 1-2 minutes or until the onions have softened up. Chop and stir every so often, but let the mean get nice and browned.
Once browned, shape your meat and onions into rectangular shape to match your roll. Add 2 - 3 slices of vegan American cheese on top. Then add a little water to the pan and cover to steam and melt the cheese.
Once melted, split open a hoagie roll. Hollow out the middle a little. Toast the roll if you wish and then give it a good healthy squirt of both ketchup and vegan mayo. Then fill it up with as much cheesy meat as you'd like, followed by the lettuce and tomato. Wrap up that sandwich and dig in!
