Hmmm, I never thought of it in this way before, but I agree with your friend. Eggs are the dish of crisis. I know when my mom can't figure out what to make or if there is a lack of meat/veggies, she'll make an omelet, which everyone in the family enjoys. We put dhania, onions, tomatoes, green chillies in the omelet. But before pouring the egg mixture in, we cut up potatoes in small pieces and fry them for a while.....and then add the egg mixture. The combination of slightly crispy fried potatoes in an omelet is YUM. Next time, I'd like to try adding a cheese (maybe swiss or pepperjack) to it...and mushrooms.
We also make simple curry with boiled potatoes. And to that we just add boiled eggs. And I've never tried making a quiche, but it's an alternative egg dish:) Interesting topic:)
