I certainly do! When I brought some leek a while ago, having in mind that RJ and I were going to cook together again on the weekend, I ended up eating it alone - RJ's cold had gone from better to worse, and we did not see each other at all for two weeks. Of course I did not want to let the leek and mushrooms and eggs to waste, so I threw everything together on the Sunday for myself.
The leek had to go into the pan with a bit of oil first, because it takes longest.
No need to add any liquid; once the mushrooms go in and heat up, they will release enough moisture to avoid sticking to the pan and burning (keep stirring, though).
While leek and mushrooms were making themselves comfortable, I put the eggs in a small bowl and added salt, pepper and some herbs, and then poured the egg mixture over the leek and mushrooms.
From then on, it is non-stop stirring until the egg has the right texture; of course it only takes a few minutes, so the mushrooms and leek should be as good as done before the eggs are added.
Nothing further was needed, since this was rather a large portion; it would have easily fed two, with the addition of a few slices of bread maybe, and/or sausage or anything else.
