After reading other reviews about it being bland I used 1.5 jars of French onion dip, 3/4 tbsp of seasoning salt and a full (2cup) bag of sharp cheddar. I used 1 cin the mixture and 1 c on top. I also prefer using chicken thighs to breast as it's more work but stays softer.
This isn't vegan or vegetarian but I think if you were trying to lessen your meat intake you could easily leave out the chicken.
