Nothing pairs better with mushrooms than an herby, garlicky butter. In the recipe below, the two are united as a stuffing for chicken breasts, which are basted with even more garlic butter before being baked. It might not be the perfect date-night recipe, but as comfort food, it's hard to do better.
Stuffing chicken breasts requires a bit of technique, but it's not difficult. Buy large chicken breasts and remove the tenderloin if it's still attached. Slice the chicken lengthwise through the narrower side, ensuring that your knife is inserted straight and that you don't cut through the top, bottom or other three sides. This will form a pocket into which you can stuff the mushrooms.
