A sandwich
Bitta Chicken on the barbe, don't take long to cook!
Rice, cook a big batch and leave ti in the fridge, heat up over the next few days, add some spices or flavorings when you get bored with it. Powdered Oats is a good one, bulk a shitload of oats in bulk and chuck it in a shake with a bit of Whey = Perfect Meal when your on the go etc.
Meat lovers pizza and chocolate for desert.
