Preheat toaster oven to 350°.
Combine first 4 ingredients in a small bowl; toss gently. Divide fruit mixture evenly between 2 (10-ounce) custard cups; set aside.
Combine flour and next 4 ingredients (flour through nutmeg) in a small bowl; stir well. Cut in margarine with a pastry blender or 2 knives until mixture resembles coarse meal. Sprinkle flour mixture evenly over fruit. Cover and bake at 350° for 20 minutes. Uncover and bake an additional 5 minutes or until crisp.
Note: To bake in a conventional oven, place custard cups on a baking sheet. Bake at 350° for 30 minutes or until crisp (do not cover).
