Ah, yes. Roast’n’Boast, another product not on store shelves anymore. Roast’n’Boast was from the makers of Shake’n’Bake, as explained in this 1972 commercial (appreciate time-traveling Tina Fey at 23 seconds):
So Roast’n’Boast was a combination of a roasting bag and beef seasonings, both of which you can obtain in your local grocery store at present. I’ll give a call to the Shake’n’Bake people to see if they could give me a better idea of what those seasonings should taste like.
Nevertheless, you could turn these ingredients into meatballs, bag be damned; add six cloves of chopped garlic and one scrambled egg, mix everything together loosely, form into loose-packed two-inch balls, and bake for 30 minutes at 400.
