Ciao Jeannie and welcome to DC!! We are glad to have you here, I hope you will have as much fun hanging out here just as all of us do!!
Jkath gave you a good thread to give you some idea, another suggestion from me is to buy a bulk of fresh vegetables (like onion, carrots, bell peppers, courgette, broccoli etc.) when you have a little time to spare, cut them up into the forms you usually use, for example diced, julienned etc. then pack them well and freeze them. Very often the prepping is one of the most time consuming part of cooking, this will speed up the process of your cooking inb many ways! (Another note, when you do this, cook the frozen vegs directly without thawing, it retains the texture as well as the nutrient much better this way.)
