Fruit Crisp

This year our family has an abundance of frozen apples, rhubarb, strawberries, blueberries and mixed fruit. I thought one of the best and easiest ways for our family to consume all this frozen fruit was to make desserts. I don't have a lot of time, so was looking for fast and easy recipes.  I have a Lazy Day Cobbler recipe (which will hopefully make it onto this site eventually). The other fruit dessert I thought would be easy are crisps, but I couldn't find a good "crisp" topping. I have been experimenting and think I have finally come up with something we all enjoy, so I am putting it here for the next time.

Enough fruit to cover the bottom of a 9" x 12" baking pan (can use frozen fruit, but do not use canned fruit)
corn starch (optional)
Topping
1 cup (cold) margarine
1 cup brown sugar
3 cups quick oats
approx. 1 teaspoon ground cinnamon*
*I added ground cloves when I used strawberries and blueberries. You could also use ground allspice or nutmeg, if you like.  Add as much or as little as you like.

Preheat oven to 350°.  Place fruit on bottom of pan.* If using frozen fruit, sprinkle corn starch over the fruit if you do not want a runny crisp.

In separate bowl cut together margarine, brown sugar, oats and cinnamon until it looks crumbly. Evenly spread topping over fruit. Bake approximately 40 minutes or until done.

*If you want a sweeter dessert, you could sprinkle sugar over the fruit. You could also sprinkle cinnamon on the apples.

This crisp was approximately ¾ strawberry/blueberry and ¼ apple. Our kids both asked for 3 helpings after they already ate their supper. I didn't think it was too unhealthy, so I let them.
