"cook more, then put some of them into the fridge" This is the way. But the only real way to enjoy cooking... is to don't have any issues with money :), so you have time to search the best ingredients, spend time preparing and pre cooking some of it.
Uff... if it's physical, I will said smart buys of home appliances? It does not use more than 4 kitchen utensils for cooking, but short and chopping can be simplified with their help.
