ALL-PURPOSE MUSHROOMS
Makes about 4 servings.
Note: This dish stores and reheats well. It should last for about a week in the refrigerator if kept in a tightly covered container. Reheat in the microwave, or over very low heat on the stovetop. The optional butter goes a long way for flavor.

• 4 heaping, packed cups mixed mushrooms (domestic and wild) sliced or minced, a generous lb.
• 1/2 tsp. salt (possibly more)
