Eton Mess is a classic British dessert that can be easily made using a food processor. Blend together strawberries, sugar, and a squeeze of lemon juice in the food processor to make a quick strawberry sauce. In a separate bowl, whip cream until soft peaks form. Crush meringue nests using the food processor. Layer the whipped cream, crushed meringue, and strawberry sauce in serving glasses. Garnish with fresh strawberries and enjoy this delightful and refreshing dessert.
