That is amazing to hear that you make cilantro and parsley pesto and have them handy all year. Right now I don't have a freezer but, in the next couple of years will get one and fill it with pesto!
The idea about yogurt with steamed vegetables is great -- I will certainly be borrowing that. Thanks so much for your comment and the information you shared!
I have found that having a freezer is really useful. Perhaps you can find a way to vacuum seal your pesto in glass jars.
Have a great day and enjoy your delicious pesto!
