Jalapeño Green Tomatoes?

[Shanghaisky]

I have a plethora of green romas, and a huge jar of pickled jalapeños with other various veggies. Is there a way I can add the romas to that pickled mix without a proper canning scenario? Can I prepare the tomatoes some way (or do I need to?) before adding them (quartered) to the pre-existing mix? Am I asking for trouble? Thanks!

The pickled jalaps are already open in the fridge? I would think it would be fine to add the maters to an open jar, and plan to use within a few weeks.

I have added some green (unripe) tomatoes to escabeche (carrots, onions, and jalapeños) at the end of the season. I added them at the end, quartered, and this way they didn't dissolve from the cooking. They were delicious, and absorbed the flavor and heat of the peppers, onions, and seasonings. If yours are in the fridge, it may take a while to pickle them, and get the flavor, but it's worth trying!
