Searching for recipe of the old Chi Chi's Restaurants

I always ordered the chimichanga when I went because I LOVED the sauce they put on it. I have never had anything like it since, not even close to it. It was almost like a gravy-maybe, it’s been years ago. The restaurant went out of business here years ago and maybe everywhere. Any Chi Chi’s chimi fans out there who know what I’m referring to and maybe know the recipe or have a good guess? Always wondered and would love to have it again.
