Strawberry Jello Salad

Here is a family holiday tradition that we have never done without. Cherie called at Thanksgiving time to get this recipe so that she could continue the tradition. This is my mother's recipe (Joan Olsen) that she made at Christmas and Thanksgiving.

2 (3 oz) pkg. strawberry jello
1 1/2 c. boiling water
1 pkg. frozen strawberries (thawed)
1 small can crushed pineapple
1 c. mashed bananas
1/2 pint sout cream

Add all ingredients except sour cream to jello. Stir. Divide and let half set in
refeigerator. Leave other half at room temperature. When half is set, add sour cream
gently, top with other half of jello mixture. Let set in fridge 3 or 4 hours or until
well set. My mother sometimes added chopped walnuts to this salad.
