While the beef is marinating, prepare the salad. (You can use your favorite salad recipe.)

Chop the onion. Heat a skillet on the stove, add 2 tablespoons of cooking oil, and wait until hot. Crack in 3 eggs. Add the beef and sausage, and turn the heat to high.
Mix 2 tablespoons of water into the leftover beef marinade, swirl to combine, and pour it into the skillet.
Cut the pâté and add it to the pan along with the onion.
Sprinkle a little black pepper on top. Since the beef was already cooked rare for steak, avoid flipping it too much to keep it tender.
