Chicken is fried with a simple seasoning of pepper and garlic salt before being simmered in tomatoes flavoured with basil, oregano, rosemary and thyme.
If you don't have any garlic salt use plain salt and a crushed garlic clove. Brown the garlic with the onions.
WOW! I just made this for dinner tonight and my bf and I LOVED it! This was SOOO easy to make. The most time consuming part is slicing the onion / removing fat from the chicken (although I really didn't need to do the latter...). Use the best quality balsamic you can find - and afford (it REALLY does make a difference). Next time, I'll use a better quality balsamic (the dish was a tad tangy, but I like tart, so it wasn't an issue for me), mix the balsamic, tomatoes & spices together BEFORE adding to the skillet (the spices tend to clump together otherwise) and add fresh minced garlic to the skillet as the breasts simmer (in lieu of the garlic salt called for). If you are in a hurry or don't have all of the spices on hand, substitute Italian seasoned tomatoes for the plain ones and omit the seasonings alltogether. This dish goes particularly well with garlic mashed potatoes and green beans, although, I think I'll try it with seasoned rice (i.e. chicken flavor) & steamed asparagus or broccoli next time to change things up a bit. - 01 Jan 2007 (Review from Allrecipes USA and Canada)
Just a note to those who aren't fond of balsamic vinegar. Try adding some chicken stock in with the vinegar to equal the 1/2 cup measurement. It's a great way to cut down on the bite of the vinegarbut, still adds great flavor. So, those who might give up on this recipe try it this way and see what you think. - 22 Nov 2006 (Review from Allrecipes USA and Canada)
I made this in the crockpot. Very easy to make. I prepped everything the night before and the next morning just popped everything in the crockpot and turned on low, the chicken was even frozen. I did use only 1/4 C. of balsamic vinegar as recommended in other reviews and I will add garlic cloves instead of garlic salt next time. Also, I will use chicken on the bone instead of boneless/skinless chicken breast if I plan on making this in the crockpot. The boneless chicken turned out dry. Other than that, the taste was very good. - 23 Sep 2006 (Review from Allrecipes USA and Canada)
