In a large bowl, add the ground turkey, onion, Worcestershire sauce, ketchup, rosemary, thyme, salt and pepper. With a large spoon or your hands, break up the ground turkey and mix it thoroughly with the other ingredients until it becomes a consistent blend.
1 lb ground, lean turkey, ½ yellow onion, 1 tbsp Worcestershire sauce, 2 tbsp ketchup, 1½ tbsp fresh rosemary, 1 tbsp fresh thyme, pinch of salt, pinch of pepper
Form meat into four large patties, packing them together with your hands.
In a large skillet or pan, heat a tablespoon of olive oil over medium heat and spread it over the pan. Once warm, add the patties and cook over medium heat, browning for about 2-3 minutes before flipping. Cook each side for an additional 3 minutes, or until the patties look brown and crisp. Use a spatula to flatten down the burgers if desired as you go. Top each patty with the cheese and allow the cheese to warm and melt for another minute. Remove from the heat to a separate plate.
4 slices pepperjack cheese, 1 tbsp olive oil
If you want to toast or warm your buns, you can place them face down onto the warm skillet for 1-2 minutes. Remove from the heat carefully.
4 hamburger buns, 1 egg
To make your aioli, add the egg, garlic, lemon juice, olive oil and salt to a blender or food processor and whip on high for about 30 seconds. It should appear thick. If it is too runny, add a dash more of olive oil and continue to pulse until it thickens.
2 cloves garlic, ½ lemon, pinch of salt, ¼ cup olive oil
Assemble the burgers on top of your buns with a generous helping of aioli and tomato. Add greens if you'd like!
