Bordertown Burgers With Spicy Onions

• 1 tablespoon vegetable oil
• 1 large sweet onion, halved and thinly sliced
• 4 tablespoons chipotle hot sauce (I use Tabasco brand)
• 1 tablespoon Worcestershire sauce
• 1 1/2 lbs ground beef
• 1/4 cup cilantro, chopped
• 1 teaspoon salt
• 4 slices monterey jack pepper cheese
• 4 hamburger buns, toasted

1. Heat the oil in a medium-size skillet over medium heat.
2. Add the onions and cook until golden brown (5-7 minutes), stirring often.
3. Add the Worcestershire sauce and 1 Tbsp of the chipotle sauce, stirring well to evenly coat the onions. Then remove the onions from the heat and keep warm.
4. Combine the ground beef, cilantro, salt, and 3 Tbsp of the chipotle sauce (Use 2 Tbsp for milder burgers) and shape into 4 burgers.
5. Grill over medium-high heat. (Approx. 4 minutes per side for medium-rare. 5 minutes per side for medium-well.).
6. Top each burger with a slice of pepper-jack cheese and grill until the cheese melts.
7. Place the burgers on toasted buns, and top with the spicy onions.
8. Add any burger toppings you're fond of. I like a little bit of horseradish mayo on my burgers.
