    This was delicious! I shredded my chicken and sautéed my onion and red pepper to make them softer. char9 is a slave to dietitians who in realty know little about nutrition. It's not their fault. They are taught by teachers who are old school. My mother and grandma lived happy and healthy into their 90's eating meals, just like this!

    This was spectacular! My husband gave it top reviews and said to be sure and make it again and again! The flavors are interesting and a little out of the ordinary; every bite is a pleasure! It's easy too!

    This was a great family recipe. I substituted for items I had on hand using turkey and cream of bacon soup. I threw in some leftover green beans and seasoned it with garlic powder, salt and pepper.

    This is a very good casserole. I read the reviews and cooked the onions with the chicken to avoid them not being done. Seasoned salt was subbed for steak seasoning. I also made my homemade substitute version of consensed soup since I don't purchase it.

    For those asking what to use in place of steak seasoning - garlic salt plus some pepper. You could also use just plain salt and pepper. The steak seasoning has coarsely ground pepper in it, but any salt and pepper will do.

    This dish is delicious! Minor changes that I made: cooked chicken tenderloins and then shredded them instead of cutting... just prefer the texture. Not a huge fan of onions, so used a T. of dried onions. Also used fresh red peps instead of jarred roasted. My son actually commented, " The peppers are a nice touch!"

    I see in the reviews someone asked what to use for "STEAK SEASONING" but I don't see a response . I want to make this but I am holding out until I see an answer.
