No I've never tried broccolini but I've seen it -- I'll have to give it a try!!
Well, with the zucchini I like them better when they're small. I get them next to the yellow squash in the grocery store & they just call them green squash. The big giant zucchinis don't taste as good to me.
A great combo with chicken is asparagus tips (I get em frozen at Trader Joes' for $1.99 a bag) sliced green & yellow squash, peppers with peppers & Green Tabasco sauce & a little olive oil.
