"Stupidly Simple Omelette" 
Get a good quality jar of pesto, doesnt really matter what it's made with.
I've been using:
pumpkin seed pesto / tomato pesto / wild garlic (Bärlauch) pesto
# add one spoonful of pesto to two large, or three medium, eggs per person (I havent tried this with large amounts of eggs, you may need to add less pesto).
# whisk.
# fry at low temperature, ideally with a good olive oil. When it's nicely set towards the sides, you could stick it under the grill for a minute or two to get the middle to set - then flip it, and give it another minute or two in the pan.
The intensity of the pesto makes for a really tasty omelette.
You can make a meal of this by adding cubed (cooked) potatoes and chopped (cooked) green beans.
An omelette with two or three eggs works well in my 18cm pan -- that's 7&1/8 inches (the base is about 13.5cm).
For two people, I prefer to make two small ones - but best experiment with your frying pan/s.
I have a couple of lovely carbon steel frying pans - that's iron that rusts, and *not* cast-iron. You can get them dirt cheap
here (amazon.de), but the equivalent seems to be difficult to find on amazon.com
Great for omelettes, fried spuds, etc.
