This is an easy and delicious Cream sauce for use with pasta or poured over most any protein.
Mince 1 shallot and saute in olive oil until soft. Rinse, pat dry, cut off stems and then slice shiitake mushrooms. (Remember they shrink a bit while cooking so plan for that.) Add mushrooms to pan with shallots and toss. Add 1/2 cup chicken broth and simmer until broth is reduced by half. Stir in 2 heaping tablespoons of light sour cream and stir until everything is coated evenly. Salt and pepper to taste. Toss with pasta or spoon over chicken, fish or meats.
