Honest, I looked when I saw your request the other day but have to admit I only looked at the back index pages and didn't see one. I left a few of the issues out and was just looking through them this afternoon. I turn a page in the Jan/Feb 2000 issue & there's a wonderful picture and a recipe. Not sure it's the one you're looking for since you said chicken and this calls for beef but thought I'd pass it along anyway.

TACO PIZZA

Convenient prebaked crust makes this tasty taco pizza as easy as can be.
