Those are ingredients. Although, there probably is an argument for Apples and Eggs being a food (seperatly).
I am fairly particular about what I eat.
I like Lasagna, augraten potatoes, hamburger cassarole, pizza, and many other things with mixed food types.
And it's not all just based on taste.
Texture plays a role in that as well.
I use onion powder in my spaghetti sauce, but I hate the texture of onions (raw, boiled, sliced, fried, etc) ((although, I like the fake onion rings from Burger King 🤔 ))
I don't like bones in my food either, but I like chicken strips form KFC.
For me, Steak or Potatoes don't have the texture to taste like spinach, or green beans for that matter.
But, I'm far from the more pickierest eater I have met.
