Heres some subs you can make from subway that are good.
Put olive oil on both sides of the bread first, and then salt and pepper on that, and a little shredded cheese after that. Get either chicken strips or steak, then put jalapenos and onions on top of that, put on some chipotle on top of that, then bacon and then put your cheese on that and have it toasted. Add whatever veggies you want. I put a small line of sweet onion on the veggies to bring out the taste a little more from the toasted onions.
Start the bread the same with with the oil and salt, then ask for double meat and put steak on then roast beef on top of it, put on some jalapenos and onions and throw some bbq sauce on top and put whatever cheese you want and have it toasted. Then add whatever veggies you want.
Once again start the bread the same, and ask for a double meat sub with salami and pepperoni on it first, then put meatballs on top of it. Put mozzarella cheese on it and have it toasted. Add whatever veggies you want and bam, ****** pizza sub.
Get one of the personal pizzas and put jalapenos on it and more cheese then have it cooked. When it comes out, put some meatballs on it and some lettuce. Request that it not be cut into pieces. When you get it, just fold that bitch and now you got a badass pizza meatball taco thing. Not a sub, but still good!
