Ingredients
Method
- Preheat the oven to 400°F. Season chicken breasts with salt and pepper on both sides, then coat with olive oil and scatter garlic cloves around them in a baking dish or sheet pan. Roast for 25–30 minutes until internal temperature reaches 165°F at the thickest part. Let rest for 5 minutes before slicing.
- While chicken roasts, melt butter in a medium skillet over medium heat. Add sliced shallots and cook for 4–5 minutes until softened and beginning to golden. Add fresh thyme sprigs and stir briefly (about 30 seconds) so the herbs release their oils without burning.
- Pour in white wine and let it bubble vigorously for 2 minutes, scraping up any browned bits from the bottom of the pan with a wooden spoon. Add chicken broth and simmer another 3 minutes until reduced slightly—aim for about ⅓ cup remaining. Remove thyme sprigs and stir in Dijon mustard. Set sauce aside to rest while you assemble sandwiches.
- Toast bread slices in a dry skillet or toaster oven until golden on both sides (about 2–3 minutes per side if using a skillet).
- Slice roasted chicken into thin strips against the grain. Place provolone on two of the toasted bread slices, then top with chicken and arugula. Pour sauce generously over everything. Top with remaining bread slices, press down lightly, and cut diagonally. Serve immediately or wrap in parchment paper for later.

Notes
The reason I keep coming back to this one is that it tastes like something from a deli counter but takes fifteen minutes to put together. You roast the chicken with simple seasonings, make a quick pan sauce with shallots and thyme, then layer everything on toasted bread. It's not complicated, but it's got more going for it than just piled-up ingredients.
The trick I've learned is letting the sauce rest after you make it before pouring over the chicken—it thickens slightly and distributes flavor better that way. If you're making this ahead of time (which works well), keep the sauce separate until assembly so the bread doesn't get soggy.
