We all need to get protein, fat, carbs, vitamins and minerals. The humble potato is one way to get protein, with a little help from dairy or beans. How do you combine foods to get your nutrition.

Think of your plate as a clock(not digital one, an old fashion one with actual numbers)
If you eat a lot of potatoes like Pear.
You're might be getting too many carbs and not all carbs are good for you either.
That lovely potato has more vitamins in it if you leave the skin on it.
And don't wash it harshly. dirt won't hurt you much, unless it has a lot of pesticides on it.
Back to the clock idea, you eat with your eyes first.
If it looks good, chances are it will taste good too.
Dark leafy vegetables like spinach, kale has lots of good stuff for you... iron, B vitamins.
Carrots is another good vegetable it has a natural sugar that won't spike your sugar unless you eat a boat load of them.
Carrots also have Beta cardoin in the them which is good for eyes, nails.
Proteins, eggs, lean meats etc.
You would be surprised how much food is a 1/4 cup of a vegetable, rice etc.
Variety is spice of life, change up your vegetables, meats
I try an new fresh vegetable every month, same with different meats, different ways to prepare the food helps too.
Food should be fun, tasty, plentiful.
Hope this helps you.
By the way this is what I do for myself.
I love to cook just don't like to do dishes.
