Every time I go to the grocery store it seems like there is a new bag in the frozen section with pasta meat and veggies. All claiming to only require a single skillet to prepare ... or "one pot meal" printed on the side. I can't help but wonder if people realize they could buy the ingredients much cheaper and prepare all but the pasta in that one skillet or pan. I do it all the time, just brown the meat. and remove it from the pan, then add my veggies and cook them, all while my pasta is boiling in a neighboring pot. It's simple to strain the pasta and add it right to the skillet everything else was cooked in then top with the meat and a sauce.
A simple soapy brush around the pasta pot and a rinse of the strainer and they are clean. I don't even need to use the dishwasher it's so easy. My meal is in that single skillet those bags brag about and I can make enough to feed a family without buying 2 expensive portioned for 2 people bags from the freezer section. Using fresh or frozen vegetables it is a money saver. On a busy night I usually have frozen vegetables and frozen chicken tenders on hand and that gives me the option of always having a quick meal ready in minutes combined with pasta in the pantry. There is enough for more than one meal for less money.
There are even some recipes where the pasta can cook in the sauce making a true one pot meal, like a quick skillet lasagna!
I think the secret is keeping the basics stocked in the pantry, and meats in the freezer that can be quick thawed.
