The best part about this recipe is that it is an old recipe from the 90s, back when moms would trade their tried and true recipes with each other. The past-down church recipes are always the best.

Can you substitute Rotisserie Chicken?

Yes! I love shortcuts. Rotisserie chicken usually has a delicious flavor all of its’ own. If you do that, then for added flavor you might want to pour some chicken broth into the water you boil spaghetti in.
