do you have a refrigerator or any other kitchen equipment to work with?

If you have an oven:
GRANOLA (5 cups)
2 1/4 cups quick-cooking or regular oats, uncooked
1/2 cup instant nonfat dry milk powder
1/2 cup sunflower seeds
1/2 to 1 cup chopped nuts (your choice)
1/2 cup wheat germ
1/2 cup firmly packed brown sugar
1/2 cup butter, melted
1/4 cup honey
1/2 cup raisins, chopped prunes or chopped apricots
M&M's, optional

Combine first 8 ingredients. Place in a large jellyroll pan & bake in a preheated 300° oven for 40-50 minutes or until golden brown, stirring frequently. Stir in raisins or other fruit. Cool. Store in an air-tight container in a refrigerator. Add M&M's. Good alsow with yogurt & fresh fruit.~~
