Granny's Meatball

Got a dish at Restaurant La Buche in Québec City called La Boulette À Mamie — beef patty, mashed potatoes, caramelized onions, sautéed peas and maple bacon, red wine meat gravy (wish I showed it better but it’s on the potatoes back there😆). I’d like to recreate something like this back home. Smelled and tasted as good as it looks on the plate, no filters necessary;)
