Anyway, my point is, I had a really lovely birthday, and while I didn't have this for my birthday supper, it is one of my favorite suppers to have.
While your chicken is browning, mince up your garlic; after your 5-7 minutes, flip the chicken over, and let the other side brown for another couple of minutes.
Look at all of that yummy, flavorful juice in the bottom of the pan! How about we bump the flavors up? Add in the garlic, add in all of the herbs/spices and spinach, and cook for about two minutes - at this point, if you are going to use a slow cooker, move all of this to your slow cooker instead of leaving it in the dutch oven.
Add in your crushed tomatoes, and your diced tomatoes, giving this a good stir, to make sure that everything is well incorporated. Put your chicken back in, and pour the chicken stock in over everything, and try your best to stir it in together, but don't knock yourself out, I just kind of stick my spoon up under the chicken and move it around a bit. No big deal. Cover this, and let it simmer, over medium-low heat, for 2-3 hours (or, in a slow cooker, on high for 2 hours, or low for 4-5 hours).
This chicken will be tender, juicy, and packed full of flavor!
