Before I begin, I should stress that I do know how to roast veg!
I make my own lunch quite often, and I'm always on the lookout for quick dinners too. I'm vegetarian, and an easy way to jazz up a sandwich/make cous cous etc is to put roasted veg on it. I've been buying those jars of sundried tomatoes, also peppers: I get these jars from the olives section. Anyhow, strikes me that it's not rocket science, and surely I can save money and do this myself?
So, if I make a roasted veg mix, how can I store it? The jars sell them in olive oil I think, but is there anything I need to know or do? Would they freeze? Or can I have a large jar on my work surface all ready filled with roasted (or whatever) veggies, ready to throw on cous cous or a sandwich?
Also, I once went to a French market in Wimbledon (!) and bought a jar of courgettes which were somehow preserved - maybe pickled, or maybe roasted? Any ideas, and can I recreate this at home?
I always mean to do this. I'd have thought that simply ensuring they are entirely covered by olive oil would work and that they'd keep for at least a week or two like this. I buy fresh pesto from a deli and they always tell me that as long as the top is sealed with olive oil, it will last for weeks, which isn't that different.
