Tip: If you make sure to cool the eggs down completely it is very easy to remove the yolks. Simply turn one egg half after another with the yolk side down, squeeze gently and the yolk should pop right out.

Basically, you can use as much eggs, avocado and bacon as you want.

I like to add some low carb ketchup and mayonnaise on the side too, but it is not mandatory.

You may also spice this dish up by adding dried chili flakes.
If you want the meal to be more saturating you could also add some shredded cheese before putting the baking tray into the oven. Gouda or cheddar cheese would fit pretty well.

You can check if the omelette is done by poking into it with a chopstick.
If you pull out the chopstick and it is clean your omelette is done. If there are moist residues from the eggs on the chopstick the omelette needs a few more minutes.

I used frozen spinach that I thawed in the microwave before adding it to the pan.
If you use fresh spinach you don't necessarily need to precook it, but give it a few more minutes of frying in the pan.

I like to eat this dish with some cream cheese on the side.

You may also add shredded cheese on top right before you put the pan into the oven.

If you don't have a food processor,  just squash the avocado with a fork instead and cut the onions into dices. Then, thoroughly mix these in a bowl with the other ingredients and seasonings for the beef mixture by using your hands or a mixer with dough hooks.

Of course, you can also use cream instead of cream cheese, combine them or even add "normal" cheese that dissolves into the soup.
