1. Wash, drain and hull strawberries. Cut them lengthwise into 1/4-inch slices and place in a large glass bowl.
2. Shortly before serving, mix in the sugar, liqueurs and pepper. Let the mixture stand until the juices start to come out of the strawberries, about 10 minutes. Scoop the yogurt (if using) into martini glasses or bowls.
3. Spoon the strawberry mixture over the frozen yogurt. Grind a little more fresh pepper on top and serve immediately.Serving Size: 1/2 cup yogurt with berries
