In a large mixing bowl, add the beef, crackers, egg, lemon juice, Worcestershire, steak seasoning, cheese, & peppers. Mix together until the meat mixture's evenly combined.
Layer two large pieces of foil on a clean countertop- enough to cover, close, and seal a burger sized pocket/packet.
Divide the meat mixture into roughly four even balls. Press on ball out between your hands to flatten it into a large patty.
Add 1/4 of the sliced onion to the center of the foil sheet, spreading out slightly. Set the hamburger patty on top of the onion.
Spread 1/4 of the carrot sticks over half of the burger patty & 1/4 of the potato slices over the other half.
Top with two slices of bacon, and season with salt & pepper to taste.
Wrap up & seal the packet tightly, then transfer it to a waiting baking sheet. Set the packet down seam side up.
Repeat with the remaining three hamburger patties.
Bake them in the oven at 350° for 45 minutes.
Carefully remove the baking sheet from the oven, and let them packets rest for a full 5 minutes before very, very carefully opening them using tongs. There will be pent up steam, and it can easily burn when it escapes if precautions aren't taken.
Serve with your favorite condiments and enjoy!
