Personally, I'm a scrambled egg person. I will mix my eggs without any seasoning in them. I will preheat my shallow cast iron pan with a ton of margarine and water, and let the water start bubbling. I will add the egg mixture into the water. The eggs will cook practically instantly, then after that it's just cooking off as much water as you want cooked off. I'll usually add cheese and green onions, but if I have them I will add crumbled potato chips. (taken from The Bear, great idea) Add salt and pepper at the end
This Cantonese scrambled egg preparation is terrific
I also really like making frittatas if I'm making something more substantial. Just saute whatever veggies you want in a couple batches on medium high, put all the veggies back and bring it down to medium low, put shredded cheese on top till it starts to melt, put in whatever herbs you want til they're fragrant, then add salted beaten eggs until the edges start to set and toss it in an oven at 400F until the egg is set (like 15 minutes). Top with some more herbs and a sour cream/hot sauce mixture and voila
