I used broccoli instead of spinach, as my husband doesn't like it & it was good. Really messy to make, tho I think this was because I didn't buy the right chicken breasts, I bought the thin kind. I didn't know that meant smaller, it had a great flavor tho. I seasoned the cracker crumbs before rolling the chicken & since I had some of the "stuffing" left over I rolled it into small balls as best I could & rolled it in the cracker crumbs & cooked it with the chicken, they were good also.
Will make this again.
