You don't always need to cook spinach! You can buy bags of baby spinach, washed and prepared in most supermarket chains which taste good raw in salads, straight out of the bag - they're not bitter like some green salad leaves. Add whatever you want to them or nothing at all; cheese, croutons, tomatoes, cucumber, peppers, olives anything, then eat with or without a salad dressing poured over the top. Yum :)
Cooked cabbage can be shredded and steamed and mixed into mashed potatoes or you can even fry them with a bit of chopped garlic or bacon thrown in.
