I know what RPcooking is talking about, but it's possible the steam and moisture coming from the raw veggies added some moisture circumventing the dryness always possible with venison.
I'll bet the veggies being nice and hot but still fresh crunchy was really good.
I didn't see any mention of seasonings
I have some cubed deer in the freezer that needs eating. This may be something I do...but I'm really leaning Swiss steak for the cubed stuff.
I'm getting ready to post something very similar...check it out here in a little while.
