Grandma Carols' Pineapple, Strawberry and Raspberry Jello

YIELD: one 9x13 pan

2 large raspberry Jello boxes (I like to use one cranberry and one raspberry)
4 cups boiling water
1 large can crushed pineapple
pineapple juice from can reserved plus enough water to make a total of 4 cups cold liquid (my can had about a half cup of juice so I needed an additional 3 and 1/2 cups water to equal the required 4 cups cold liquid)
sliced strawberries (I use a full container of strawberries)
raspberries (I use about a cup or two of frozen raspberries)
OPTIONAL: chopped walnuts (I use chopped pecans since walnuts give Craig cankers)

Talk about easy- mix Jello and hot water until Jello is dissolved. Add cold pineapple water mixture to the Jello mixture. Pour about half of the liquid into a 9x13 pan. Add strawberries, raspberries and nuts. Place in fridge. AFTER, pour the remaining Jello mixture into the pan as it will make things so much easier to not try and carry a full pan of liquid from the counter to the fridge and have the great possibility of spilling some of it. Refrigerate overnight. Serve cold.
