Where Did the Spinach Go?

Tonight I made. spinach for dinner. Since it is just me and Carter I thought that the big bag of baby spinach would be enough. I piled the whole thing in my biggest skillet and in less than a minute of turning it with tongs it was cooked. It might appear to be a magic trick because the over flowing pan of greens turned into a tiny pile that took up one eighth of the pan. I grated a little fresh nutmeg and salt and peppered it. It was tasty, but it was little.  
I know that frozen spinach is the deal of the century, but I really don’t like the big steamy chopped spinach unless I am putting it in a quiche or something similar like a soufflé. To just eat straight I really like baby spinach, but I am afraid my car is not big enough to bring home the raw amount needed.
I guess I could just eat spinach uncooked and then the one big bag would be enough for a meal, but I really don’t love the metallic taste I get in my mouth after chewing raw spinach. Also my teeth feel like they have been coated with some strange lacquer after eating it raw, but cooked never has that same effect.
I am not batting a thousand in my greens cooking this week, between my gritty Swiss chard and disappearing spinach. I am tired of green beans and broccoli and well asparagus has been good, except for the smell when I pee.
I guess I am searching for a brand new green vegetable. Not a starchy one like green peas or fava beans, but one that practically has a negative calorie count. I don’t really like celery, and artichokes are not really in season.
I eat enough arugula everyday at lunch to keep me regular. I just want enough green vegetables to fill two thirds of my dinner plate so I feel like I had an actual meal. The tiny pile of spinach did not fulfill the requirements tonight.
