Whenever I go to Washington DC., I stop by this little sandwich place right by the station (or more like a bus parking lot drop off place since I take the Megabus). There they have freshly roasted whole turkey breasts and hams that they carve up and add to sandwiches. It is the most amazing sandwiches that I have ever had. Having not gone to DC in three weeks, I decided to make an at-home version of the sandwich but with chicken breasts instead of turkey.
Ingredients: 1 onion thinly sliced, 3 tablespoons Worcestershire sauce, 1/2 cup chicken broth, 3 tablespoons room temperature butter,1 tablespoon fresh thyme, 6 chicken breasts, 6 bread rolls, 6 slices of Havarti cheese, soft butter for rolls, salt and pepper to season
Preheat oven to 400. Begin by mixing the onion with Worcestershire sauce and chicken broth. Allow to marinate for 10 minutes and add to a baking dish.
Roast for 20-30 minutes or until the chicken is cooked. Slice the chicken breasts and drain the liquid into a separate container. The sauce can be left aside for dipping later if you like that. Butter the bread rolls and top with chicken slices.
