Cook the Slimming Beef Sausages in a non-stick frying pan over medium heat for 10-12 minutes, turning frequently, until they are browned on all sides and cooked through. Set aside to cool.
Spray the same pan with low-calorie cooking spray and cook the onion and red pepper for 5-7 minutes until softened.
Cut the Slimming Beef Sausages into slices and arrange them in the bottom of a 23cm pie dish along with the cooked onion and red pepper.
Whisk together the eggs, fat-free natural yogurt, grated cheddar cheese, paprika, salt, and black pepper in a mixing bowl.
Pour the egg mixture over the sausage mixture.
Bake the quiche in the preheated oven for 25-30 minutes, or until the filling is set and golden brown.
