I was going to use our cooker tonight for 2nd time. I was thinking of using sliced chick breast, but its still in freezer - so you think I should still make it? I guess I can put it in frozen (thought it had to be defrosted first - thats what the instruction book said) and cook for lesser time, but do I still cook on low or put it on high? I was going to put pumpkin, mango in with it to make some sort of mild curry...
