Chicken with Sweet Potatoes

I just threw this together and my husband raved. So I thought i would share 

1 tsp hot sesame oil
1 tbl EEVO
1 medium yellow onion chopped
3 boneless skinless chicken thighs cut into 1 inch chunks
1 sweet potato, peeled and cut into large chunks
1 clove garlic, minced
1/2 cup red wine
1 sweet red pepper, sliced
Fresh ground black pepper (optional)

Put the oils in a skillet and heat on medium high heat. Throw the onions and garlic in and cook until soft. Add the chicken and the potatoes and cook until the meat is browned. Add the red wine, lower the heat a bit and cover until the potatoes are soft - about 5-10 minutes. Add the red pepper and take off the lid, turn up the heat and cook until the wine is reduced to almost nothing. Serve with a grinding of black pepper, if desired.
