Recently diagnosed with Type 2 Diabetes, so still learning what my staples are. But eggs, strawberries, and grapes have become a pretty regular eat.

Rice.

…multi-whole-grain sourdough and way more dairy than i should be eating…

Red lentil, yellow lentil, black lentil, urad lentil, chick peas (white and black), kidney beans, rice, tofu, potatoes, canned tomatoes, coconut cream and prefried dried crispy onions. With those I can make a large variety of foods and sauces. Usually just adding some other veg like peppers, carrots, leaks, etc

Edit: I forgot to list Tamari and Marmite. Good for various things, but combine those in proper proportion withan fried onion base and a flour roux, you have a beefy stew base or brown gravy

EGG.

(-protein has one of the highest bio available properties and I think most, if not all trace nutrients essential for human body excluding vitamin C)

Eating EGGs plus a vitamin c source is very fucking healthy.
