Season the chicken (4) with salt and pepper. Heat a large saute pan to medium-high and add about 1 tablespoon of olive oil. When the oil begins to shimmer, add the chicken and quickly saute until just browned. Remove to a plate.
In the same pan, add another tablespoon of olive oil and saute the onion (1) until they just are soft and translucent. Add the garlic (2 tablespoons) and saute for 3 - 4 minutes. Add the mushrooms (2 cups) and saute until they are soft. Add the tomatoes (1 can), tomato sauce (1 cup), sugar (pinch), wine (1/3 cup), balsamic vinegar (1/4 cup), basil (1 teaspoon), and oregano (1 tablespoon) and simmer the sauce for about 10 minutes for flavors to marry. Stir in the artichokes (1 can), olives (3/4 cup), and the chicken and continue cooking until the chicken is cooked through (It took me about 10 minutes. The exact time will depend on the size of your chicken chunks.) Season to taste with salt and pepper.
Serve with hot spaghetti (1 pound) and a sprinkle of Parmesan cheese. And LOTS of Italian bread

Notes
Don’t overcook the chicken in the first step. It finishes cooking in the sauce, so just aim for golden edges, not fully done pieces.
Let the sauce simmer. Those 10 minutes matter — that’s when the wine cooks down and the tomatoes deepen in flavor.
Add pasta water if needed. If your sauce thickens too much, a splash of starchy pasta water loosens it while keeping everything silky.
Fresh herbs are great if you have them. A little chopped basil or parsley at the end adds brightness and makes it extra pretty.
