I know about the dog recipe websites but?

What is a meal I can feed my dog twice a day that will give him all the vitamins and nutrients he needs? I want to make his own food but don’t really have a lot of time to buy 500 different ingredients. I barely have time to cook my own food because I’d rather play with him and give him attention since he stays home in a crate for 8 hours of the day.
My dog is about 27-30 lbs
