Which foods are named twice. I can only think of Couscous and Yum Yums. Any others?

You're right, "Couscous" and "Yum Yums" are indeed examples of foods named twice!

Here are some other examples:

* Biscuits and Gravy: "Biscuits" is repeated in the phrase.

* French Fries: "Fries" is a shortened version of "French Fries."

* Peanut Butter and Jelly: "Peanut Butter" is repeated.

* Macaroni and Cheese: "Macaroni" is repeated.

* Chicken and Waffles: "Chicken" is repeated.

* Fish and Chips: "Fish" is repeated.

* Spam and Eggs: "Spam" is repeated.

* Snickers and M&Ms: "Snickers" is repeated.

* Jelly Beans: "Jelly" is repeated.

Let me know if you'd like more examples! 😊
