Easy, highly versatile, long shelf life, balanced nutrition: 90 microwave rice pack + Frozen veggie mix/stir fry mix + Canned chicken/tuna/mackerel/precooked sausage + Premade sauce or seasoning

I've been relying on this heavy lately, I like to rotate veggies and sauces to make different cuisines to keep it interesting, "asianish" "mexicanish" "mediterraneanish" etc

If you buy off brand everything like I do it's pretty cheap too lol
