would in a conventional oven. As always, to ensure the meat is cooked use a food thermometer to ensure that it has been cooked to the right temperature. Check out the charts on my web site to find the recommended internal cooking temperature for the various kinds of meat. Use the manual that comes with your microwave to check how long the meat should be cooked and how much standing time is required. Standing time is the time the food requires to finish cooking once it is taken out of the microwave oven. Can I heat pastas that I cooked few hours ago?  How can I cook them so they would be good? Pasta can be cooked ahead and refrigerated or frozen. It should be slightly under done and then put into boiling water, just long enough to heat through, 2 to 3 minutes. Hi!  I purchase ground meat to make meatballs that I freeze afterwards.  I would like to know if after cooking them a first time in a soup, I can warm it up and consume it the day after (or in two days) without any problems knowing that is was kept refrigerated?  I live in the USA and the meat that I buy comes on a deep tray vacuum packed and has a best before date good for up to a week (meat stays red).  What do you think of that?  Thanks! I assume that you make your meatballs from the fresh ground beef and freeze them
