This is a traditional Cincinnati recipe of German origin and although it may seem like the ingredients shouldn't work well together, I promise you they do and this dish is remarkably good.
Brown a cut up broiler in olive oil with the rind of a grapefruit and an orange cut into julienne strips. When chicken is browned, put it in a deep cassarole dish or a dutch oven. The chicken will only be partially cooked at this point.
Next dice up 1/2 cup onion
1/2 cup celery thinly sliced
1/2 cup green pepper
2 cups stewed tomatoes or 2 cups diced fresh tomatoes
the pulp and juice of both the grated orange and grapefruit
Put all ingredients over chicken.
If it doesn't seem to have enough liquid, you can dissolve 1 boullion cube, chicken flavor, in 1 cup water and add to vegetables and chicken.
Cover and put in 350 degree oven for 1 hour.
Excellent when served over rice.
