is there a mustard pickle recipe using green&yellow beans and/or cucumbers?

I have already made dill pickles & bread & butter pickles. now I want to make a relish or similar to put on sandwiches. At the moment i have too many cucumbers and green&yellow butter beans so want to use them.

What is a good recipe for a mustard and/or tomato based bbq sauce?

I’m looking for good bbq recipes, any good ones out there?
