Wash strawberries, drain off water, and slice. Place into a bowl and sprinkle with 2 tablespoons of sugar. Let the strawberries stand at room temperature for an hour or so to macerate. Optionally, you can use frozen sliced strawberries. Just thaw and add when jello has cooled.
Dissolve jello in 3/4 cup of hot water in large bowl. Let cool at room temperature.
Add whipped topping and strawberries to the jello. Mix well and pour into the crust. Refrigerate until well chilled, 1-2 hours, before slicing. Garnish with sliced strawberries if desired.
