I am looking for some suggestions for recipes that meet the
following:

1) be able to cook a large quanity at one time so I can freeze a
dozen portions to eat .

2) the preparation should consist of a few labor intensive tasks. I
like to listen to audiobooks while cooking. So if I can do a
repetitive task for 20-30 minutes then I can multi-task well. An
example would be chopping onion, peeling garlic etc.. The problem is
I already have alot of frozen garlic and onions in my freezer

3) be healthy , preferably all vegetarian.
