Halve the potatoes lengthwise, then cut each half into 5 thin wedges.
-
3
Place the potatoes and 4 crushed garlic cloves on a rimmed baking sheet and coat with about 3 tablespoons extra virgin olive oil.
-
4
Season liberally with salt and pepper and roast for 45 minutes, turning once, until deeply golden in color and crispy.
-
5
Once the fries have had a 15-minute head start, heat a skillet over medium heat with 1 tablespoon of the oil and 2 tablespoons of the butter.
-
6
Add the onions, chopped garlic, bay leaf, thyme, salt, and pepper.
-
7
Cook until the onions caramelize, 20 minutes or so.
-
8
Add the sherry and deglaze the pan, scraping up any bits from the bottom, and cook for a couple of minutes longer.
-
9
While the onions are cooking, preheat a grill pan or large skillet over med-high heat.

In a bowl, combine the sirloin with the Worcestershire sauce, parsley, salt, and pepper.
-
11
Divide the mixture into 4 portions, then form each portion into a large patty.
-
12
Coat the patties in a little oil and cook for 5 minutes on each side for pink centers, a minute or so less for rare and 2 minutes longer for well done.
-
13
Melt 2 tablespoons of the butter in a small saucepan over medium heat.
-
14
Add the shallots and cook for 2-3 minutes, then whisk in the flour and cook for another minute.

Place the bread on a baking sheet and toast on both sides 6 inches from broiler until lightly golden.
-
19
Set 4 pieces of bread aside, then mound the gruyere onto the remaining bread rounds, just like the large croutons that top French onion soup; return to the oven to melt the cheese, 1-2 minutes.

Dress the greens with the lemon juice, the remaining 3 tablespoons of oil, and salt and pepper.
