Beat together eggs with the heavy cream, salt and pepper.
In a non-stick pan over medium heat, melt half the butter and add half the egg mixture. Tilt the pan back and forth to ensure it covers the entire base.
Cover and cook for about a minute.
When you are able to move the entire crepe when shaking the pan back and forth, flip with a spatula and cook for another minute.
When fully cooked, remove and set aside. Repeat with the other half of the egg mix.
Spread the sour cream on the crepe first, then add the lettuce, tomato, bacon and avocado.
