Ingredients

• 1 pound ground sirloin
• 1 pound chorizo sausage
• 4 softs egg buns or brioche
• 1 tablespoon softened butter
• 4 ounces Manchego cheese , grated

Instructions

1. 1 Start the burgers: Mix ground sirloin and chorizo together with your hands in a large bowl until well combined. Set aside to let the flavors blend while you cook the onions and make the sauce.
2. 2 Cook the onions: Heat oil in a large skillet over medium heat. Add onions, brown sugar, salt, and pepper; cook and stir until onions are golden brown, about 15 minutes.
3. 3 At the same time, make the sauce: Heat oil in a skillet over medium-high heat. Add onion and sauté until tender. Transfer onion to a blender. Add ranch dressing, red pepper, paprika, and saffron; pulse until fairly smooth. Refrigerate until needed.
4. 4 Finish the burgers: Preheat an outdoor grill for high heat and lightly oil the grate. Form meat mixture into four patties, slightly larger than the buns.
5. 5 Cook burgers on the preheated grill until well done, about 5 minutes per side. Split buns in half and spread butter on the insides. Toast briefly on the grill.
6. 6 Place burgers onto buns and top with caramelized onions, ranch sauce, and Manchego cheese.
