As I said above, there isn't a real recipe to this. Once you know the method, you can tweak it as you see fit.
Chop up your veggies of choice. (I used a new potato and a little red onion tonight.) Heat some olive oil in a ovenproof skillet and saute the veggies until they're cooked and a little soft. (For potatoes, I cook them until they're soft, but not too brown.)
Beat eggs and a splash of milk together in a bowl.
Add eggs to pan. Add a little cheese of choice if you want. Let the eggs cook until they're mostly set. Put the pan in the oven under the broiler to finish cooking. (2-7 minutes depending on how long you let them cook in the pan.
That's it. Enjoy your yummy, easy, inexpensive dinner. This is one of those dinners I consider a "free" meal. I know it's not really free, but you're using up odds and ends in the kitchen so it feels like it's free.
P.S. I am not posting a finished product picture because it broke on the way out of the pan, and I don't want you to laugh at me.
