In a saute pan over medium-high heat, cook the diced onions and canola oil until the onions are translucent, about 5 minutes. Place the ground sausage, beef, breadcrumbs, cream, cheese, mustard, oregano, thyme, eggs and some salt and pepper in large mixing bowl. Add the sauteed onions to the bowl and mix the ingredients by hand, until completely incorporated.
Preheat the oven to 375 degrees F.
Form the meatball mixture by hand into balls slightly larger than a golf ball, repeat for the remaining meat. Place all the meatballs on a sheet pan and cook until fully cooked throughout, 45 minutes to 1 hour.
Drain all excess grease and let the meatballs cool. Serve alone with some marinara sauce, with spaghetti and marinara or in a meatball sub sandwich.
