Chicken 3 Ways - Chicken with Awesomesauce

Chicken with Awesomesauce. Served with garlic-ginger zucchini and steamed broccoli w/cultured butter

I didn't name this, my family did. It's quick, easy, and tastes wonderful.  Basically it's chicken in a sort of sauce or gravy that tastes really great poured on top of things.
First, a few notes about ingredients. We use tamari sauce in our house, because unlike most regular types of soy sauce, it doesn't contain wheat. The onions can be any kind that you have on hand, from leeks or scallions to green onions or the real deal. I mostly use the dried minced onion that comes in a bottle, because it's fast and I don't have to chop onions. Usually I serve this with veggies, most often broccoli and green beans, that have been steamed and tossed with cultured butter. It's definitely a household favorite. Oh, and the amount of chicken here works well for my family of four because not all of us are adults and because the chicken I buy at Costco tends to be large enough to split between a child and an adult. If you have more people, or want more leftovers, add more chicken but leave everything else the same. The amounts given here are mostly just guidelines. Add more or less of whatever you'd like to get the taste you want. But be careful about adding too much tamari sauce or it will get salty!
So without further ado, here is the recipe:

CHICKEN WITH AWESOMESAUCE

2 Tablespoons butter
2 Chicken breasts
1/2 small onion, diced or about 1/8 cup dried minced
2-3 tablespoons tamari sauce
1 cup chicken broth
1 tsp xantham gum (optional)

Melt butter in a pan over medium-high heat. Add chicken and brown on one side. Turn; add minced onion and brown other side of chicken. Pour in tamari sauce and stir chicken/onions. Add chicken broth- please note that you can add more if you feel it needs it - and cover to cook chicken through (if not using xantham gum just leave uncovered and let the sauce boil down as the chicken cooks). Slowly add in xantham gum, stirring thoroughly to prevent lumps. Continue to cook another 2-3 minutes or until sauce is thick. Serve with your favorite veggies.
