Marinate boneless pork roast in a gallon size baggie with Fosse Farms Raspberry Dressing. Add 10-15 large garlic cloves to marinade. Turn bag frequently during day or leave in fridge overnight. Take roast out of bag and save marinade juice. Brown roast on med-high heat in olive oil on both sides; turn to low and pour marinade juice on roast in pan and add fresh mushrooms on top. Simmer until roast is appropriate temperature.
