Caramelize the onions

• Cook the sliced onions with the butter, olive oil, sugar and a little salt over medium heat.
• Stir occasionally until deeply caramelized and golden, then set aside.

Make the burger sauce

• Mix the mayonnaise, ketchup, mustard, chopped pickles, caramelized onions and pickle juice.
• Season with chili powder, paprika, parsley, garlic powder, onion powder, salt, black pepper, cayenne and chicken bouillon.
• Set aside until ready to assemble.

Cook the burger meat

• Heat the olive oil in a large skillet and cook the chopped onion until softened, adding the garlic toward the end.
• Add the ground beef and cook until mostly browned, breaking it up as it cooks.
• Stir in the seasonings and tomato paste, pour in the water and simmer until everything comes together.
• Set aside and let cool slightly before assembling.

Assemble the burritos

• Fill each tortilla with the burger meat, a mix of colby jack and pepper jack cheese, burger sauce and caramelized onions.
• Fold the sides in and roll tightly, without overstuffing.

Crisp the burritos

• Heat a little olive oil in a skillet over medium heat and place the burritos seam-side down.
• Cook until golden and crispy, then turn and crisp the other sides.

Serve

• Serve hot with extra burger sauce for dipping.
