    In medium saute pan over medium heat, add oil and onions. Cook until brown and caramelized. Add the tomatoes, and garlic and cook for a few minutes, just to soften the vegetables. Then add the remaining ingredients and simmer for 30 minutes.

    You can either serve the ketchup chunky or puree it in a blender first and serve it smooth.

    While the ketchup is cooking, add bacon and onions in a medium pan over medium to high heat, cook until the bacon is rendered but not crisp. Add the chorizo and cook until done. Remove the bacon mixture to a paper towel-lined plate to drain and cool.

    Divide ground chuck into 8 equal parts. Form into a loose ball, and create 4-inch patties. Layer 1 piece of cheese onto the center of 1 patty. Top with 1/4 bacon mixture, another slice of cheese, then add another patty on top and gently seal edges and form into a patty, about 4 inches wide and 1 1/2 inches high. Repeat with the remaining patties to make a total of 4 large patties.

  • 5

    Heat a medium saute pan over medium heat. Place all 4 patties in the pan and cook for 3 to 4 minutes on 1 side, then gently turn over and cook for another 3 to 4 minutes. Remove the pan from the heat, cover and pop it in a 250°F oven for 10 minutes.

    Remove from oven, place onto rolls and serve with Worcestershire Tomato Ketchup.
