Here's my GF version...Delicious! I left out the cheese and bacon from the original recipe, and we thought it tasted even better without it...and it's healthier too!
Here's what I used...
2 tsp olive oil
1 onion chopped
salt and pepper
1 15 oz can stewed tomatoes, undrained
1/4 cup GF Italian dressing
3 tbsp. tomato paste
2 boneless chicken breasts cooked and shredded
HEAT oil in large nonstick skillet on medium-high heat. Add onions; cook 5 min., stirring occasionally. Add a dash of salt and pepper. Stir in tomatoes, dressing and tomato paste.
ADD chicken; cover. Simmer on medium-low heat 12 min.
I served this over brown rice.
