This was such a fun little thing to make. Obviously you can use regular syrup, sausage patties, cheese, and eggs if it's what you have on hand. It won't be as healthy, but I would imagine it will still be better than McDonald's offerings.

1 t. light whipped butter (or light buttery spread), melted
2-1/2 T. sugar-free pancake syrup
1-1/2 T. whole wheat flour
1/4 t. baking powder
1 veggie sausage patty (such as Morningstar Farms)
1 slice fat-free American cheese
1/4 c. liquid egg subsitute, such as Egg Beaters
To make pancake batter, combine melted butter, pancake syrup, whole wheat flour, and baking powder. Mix thoroughly.
Bring a skillet sprayed with nonstick spray to medium heat. Add batter to form 2 small pancakes. Cook for 3-4 minutes per side, flipping carefully, until golden brown. Transfer to a plate.
Respray the skillet and return to medium heat. Pour in egg substitute and allow to spread out evenly. Do not scramble. Once mostly cooked through, flip carefully and allow the other side to finish cooking. Gently fold in half once, and then fold again. Place cheese slice on top and allow to melt.
Meanwhile, cook sausage patty according to package instructions.
Build sandwich by placing sausage patty on one pancake, and topping with cheesy eggs and other pancake.
