I don't know who needs to hear this but in every restaurant I worked in, from fast food to the fancy french place, some ingredients came pre processed, so please don't be like "real cooks peel and chop garlic" like no we get a tub of pre peeled cloves and put them in a processor

"real cooks don't cook like that" buddy ninety percent of line cooks survive exclusively off frozen pizza and cheap beer, calm down

Also there's generally an entire position in "real kitchens" that's just prep. They make little tubs of pre cut veggies and meat that the cooks use. Often days in advance. It is not very different than pre cut veggies from the grocery store
