I'm looking for a substitute for an old produce: "Cheddar Cheese &
Chive Potato Topping"

My late mother used it in her Easy and Elegant casserole recipe and if
I rememer correctly it was really good. We have a lot of pot lucks to
attend around Christmas and would like to make this casserole for at
least one of them.

Here's the actual recipe:

Easy and Elegant

3 cups diced chicken or turkey
1/2 pound diced cheddar cheese
1 7 oz. package uncooked elbow macaroni
1 can cream of mushroom soup
3/4 cup Cheddar Cheese & Chive Potato Topping
1 small can (5-1/2 oz) evaporated milk
1 4 oz. can mushrooms, undrained
1-1/2 cup diced celery
1/4 cup chopped green pepper
1/4 cup chopped onion
Butter bread crumbs and slivered almonds

Mix all ingredients except last one. Top with crumbs and almonds.
Refrigerate overnight.
Bake at 350-degrees for one hour, covered and uncover and bake an
additional 1/2 hour.

I thought I'd try a container of prepared dip, but if someone has any
better ideas they would be greatly appreciated.

Thank you.
