Pan-roasted Chicken

1 T olive oil
1 T butter
3-4 pieces chicken
salt and pepper
1 medium onion, quartered
2 cloves garlic, chopped
5-6 plum-size tomatoes
French-cut green beans

Heat oven-save frying pan over high heat.  I like to use a cast-iron pan.  Add oil and butter.  Once butter has melted, add chicken and brown on each side for about 3 minutes.  Salt and pepper to taste.  Remove chicken to plate.  Add potatoes, onion and garlic and sauté until onions start to tenderize.  Add chicken back to pan.  Add tomatoes, whole.  Roast in 350 oven for about 45 minutes until chicken is tender.  Stir potatoes halfway through to promote even browning.  Top with green beans last ten minutes.
