The only changes I suggest to the marinated are; adding 1 tsp curry powder and using garlic pepper instead of black pepper. Next time I will also add one more jalapeno, using all but the majority of its seeds. (I like things with a little more warmth)
I took GodivaGirl's suggestion and made bacon wrapped stuffed jalapeno peppers to serve on the side excellent combination! I know I will be serving this dish often, and will use the Mango recipe for chips and salsa as well.
