New vegetables for stir fry?

i love cooking stir fry (something i've learnt from my mum). i want to know what new vegetables i can try to add to my stir fry (and what flavour they add), even other stuff e.g. kidney beans (i'm vegetarian). vegetables i've tried are onions, mushrooms, leeks, garlic, sweetcorn, spinach, cabbage, broccoli, red pepper, green pepper, yellow pepper, orange pepper, jalapeno peppers, carrots, courgette and spring onions (can't think of any more but i'll add some later if i remember). thanks in advance :).
