I want to pickle the banana peppers, jalepenos and bell peppers from my garden.  I have a small sandwich bag full of banana peppers so far, but no more than that.  Is it okay to store them in the fridge until I have more ready to pickle or should I go ahead and do something with them?  Can I freeze them while I wait? 
It depends how long you will need to store them.  A couple days in the fridge won't effect them much. After three or four days they will start to go limp. In my experience, limp, un-fresh veggies make terrible pickles.  I wouldn't freeze them. In general freezing will keep them good for a long time but they will still be a little limp when they are thawed and the pickles won't be as good.  I have dealt with the problem of small yields by preparing a whole batch of pickling brine and putting it in a pitcher in the fridge (carefully labeled to prevent surprises). Then you can very easily make a 1 jar batch of pickles without losing much time. Do water bath processing in a smaller pot that will still contain the jar.
