I'm sure an Italian grandma would throw her hands up in horror...
And 20 minutes is to cook it. Eating time is extra - but if I 'saved time' on a takeaway I still have to take the time to eat it. If I'm on my own and don't have NT to wash up the pans as I serve, then there's five minutes to wash up a couple of pans and a wooden spoon and a fork...
Nigella Larson would be proud, I however, cook from scratch. Almost nothing I use comes from a can except for black beans, and that's only because when I'm using them it's to add them to something that's quick, like a burrito or quesadilla. "And 20 minutes is to cook it..." illustrates my original point; if I'm trying to save time on everything except the eating part, even the rice cooker doesn't help since it has to be monitored. It's not like I could set it, go run errands and come back later to find a complete meal waiting for me. As for the washing up, thank heaven for paper plates!
