Ingredients

• 1 1/2 cups finely crushed saltine crackers (saladas) (from 1 sleeve, about 37 crackers)

• 2 Tbsp. granulated sugar
• 2 large egg whites, lightly beaten
• 1 (14-oz.) can sweetened condensed milk

2. Transfer mixture to a 8x8-inch baking dish lined with cooking spray; firmly press evenly on bottom. Freeze 15 minutes.
