I cooked a large batch of chickpeas and froze the unused leftovers in 1-cup portions. What is the best way to thaw them? Does the microwave significantly effect quality? I prefer a quick thawing method, if it doesn't negatively effect quality too much.
Microwaving on low power is probably OK, but if you want to be totally safe you could put the chunks into a large Ziploc bag and float them in a tub of warm tap water--not super quick, but likely to be quicker than just setting them out on the counter.
I'm going to venture a guess and say that since the beans are already well-cooked (as all cooked beans are), microwaving won't hurt them a bit. You don't want to microwave frozen meats and such because you don't want to cook them, but you dont have that problem with cooked beans.
I haven't tried this, but I can't see how it would affect the beans in the slightest.

There isn't any such thing. Put them down in the fridge when you go to work. When you come home, boil some water and drop them in for a few minutes until heated trhough...
