I'm afraid my beloved children are freaks: They hated mac n' cheese. I made it twice, once pretty cheesy and the other with just a white sauce and a hint of cheese. Nope, and nope.
They do like sweet potato pancakes, quesadillas with tomatoes, yogurt with fruit (esp. Brown Cow), dried apples, and oatmeal.
I gave my daughter creamed spinach once, and for days she was deeply suspicious of anything coming at her on a spoon.

If this persists when she is older, she's going to have a tough life as I really like spinach and add it to a lot of things.
