A jar of fresh made ghee (butter oil) where the jar was sterile and sealed properly will last for a hundred years.

Basmati Rice, stored properly, will last indefinitely. It is the king of rice, cooks in 12 minutes, easily digested and tastes like popcorn.

Dried Beans (lentils and mung beans fast cooking and most digestible) stored properly, will last decades. High protein and easy to digest.

Wheat berries store for 10-20 years. Just need a grinding mill to make flour as you go.

Canned vegetables are good for 5 years. I have carrots, green beans, spinach, corn, tomatoe, potatoes, etc.

Properly freeze dried vegetables likewise but you might need to do it yourself to do it right.

Salt, Pepper, cinnamon, ginger, and freshly ground spices like those in mixed curry, properly sealed in small serving containers, will last a decade. The spices in curry are anti-inflammatory, increase digestion, anti-parasitic, anti-oxidant, and are tasty.

So quite simply you have FRESH MADE rice and beans with vegetables in a butter/curry sauce and flat-bread at the ready for super cheap, without relying on the dubious "ready made" freeze dried techniques that promise 20 year shelf life that winds up being more like 3 or 4 MAX.
