Montreal seasoning is great. My youngest daughter (6) finds it too peppery. So, i make a milder blend by mixing garlic powder, onion powder and just a bit of black pepper. She likes that.
I'm trying to slowly break her in to the spicier stuff.
That recipe is absolutely great! I also sliced up a sweet onion and put inside. Cooked it on the grill at the cabin (food always tastes better at deer camp).
