The amount of egg mixture you definitely need to increase the amount of ground beef to 2-2.5 lbs and Bacon should be from 1-1.5 lbs. I would also suggest maybe sauté some onions with the ground beef maybe 1/3 of a yellow onion. Then when combining the mixture throw in another 1/3 onion before baking. Saving the remaining 1/3 onion to sprinkle across the top along with some diced Roma tomatoes and shredded lettuce.
