Look for things you can make in a slow cooker. Decide on a couple of things on the weekend for the coming week. Buy everything you need, cut the meat and bag it, have all the ingredients ready to go. Then in the morning just put everything into the slow cooker, turn it on, and it durn near ready to eat for dinner. The decision is made and just add a couple of finishers.

To be really lazy, there are now premade seasonings especially for slow cookers. They may be a tad high is sodium so make sure and read the labels. But for a once a week meal they're probably ok to use.
