I got curious about the ingredients in the Montreal Steak Seasoning, and found this at one of the copycat sites. I'm sorry, I can't find it again to post the link.

McCormick Montreal Steak Seasoning

4 tablespoons salt
1 tablespoon black pepper
1 tablespoon dehydrated onion
1/2 tablespoon dehydrated garlic
1/2 tablespoon crushed red pepper
1/2 tablespoon dried thyme
1/2 tablespoon dried rosemary
1/2 tablespoon dried fennel

Mix together and store in a shaker. Shake or rub 1 tablespoon
seasoning onto 1 pound steaks, pork chops and hamburgers
before grilling or broiling.
