Mix the first seven ingredients well in a medium-sized bowl. Soak the ground beef in the adobo sauce for 1-2 hours. After soaking, strain excess moisture off using a colander (it's fine to have a little excess moisture, as it will steam your potatoes. Too much, and your meat patties will fall apart).
For the Hobo Dinner Potatoes:
In a small bowl, whisk together the lemon juice and olive oil. Toss with potatoes, red peppers and onions.
To Assemble:
Preheat oven to 375 degrees.
To assemble the meat patties, divide the ground beef in adobo sauce into 8 balls. Press into patties. Place 1 oz. Monterrey Jack cheese (cut in squares) on each patty. Place another patty on top, and press together to seal.
To assemble your hobo dinners, tear off a large piece of aluminum foil. Place one adobo patty on the bottom, and spoon potato mixture on top. Sprinkle with salt and pepper. Seal well.
Bake for 1 - 1 1/4 hours or until potatoes are tender.
