1. 1To prep the burgers: In a medium bowl, toss in the ground meat, ½ teaspoon salt, ½ teaspoon pepper, and Worcestershire sauce.
2. 2Cut the red onion crosswise into ½-inch-thick rounds.
3. 3Brush olive oil on both sides of all the slices.
4. 4Sprinkle with some salt and pepper.
5. 5For the lemon garlic aioli: In a small bowl, mix all the ingredients together.
6. 6Place back in refrigerator until burgers are cooked.
7. 7To cook: Preheat grill to around 350.
8. 8If using cast iron grates, use a paper towel or cloth to wipe all grates with canola oil.
9. 9Grill the red onion rounds until softened and lightly charred, about 4 minutes per side.
10. 10Place burger patties on grill.
11. 11Close lid and prep the buns by brushing canola oil on insides.
12. 12After a few minutes, check the patties. If the bottom half looks just about cooked, roughly 3 minutes, flip over, and place cheese on top.
