Rinse the chicken breasts and pat them dry with paper towels; season with salt and pepper and dredge them in flour.
In a large sauté pan, over medium heat, melt 1 tablespoon of the butter, sauté the onion and garlic for 2 to 3 minutes. Add the ham and sauté 2 minutes more. Move the mixture to a dish and return the sauté pan to the heat; add the remaining butter.
Sauté the chicken until golden brown on both sides. Top with onions and ham. Season with cumin and sage; add the wine and chicken broth. Cover and simmer for 15 minutes.
Top with capers and serve.
Notes
If preparing this recipe as gluten free, use GF all purpose flour in place of regular, and be sure to use a brand of chicken broth that is designated as GF.
Don't have any ham? Look for a thick slice of ham that you can purchase individually wrapped in your market's meat section.
