If you peel the bottom 2/5 of asparagus & cook it all together including peel. Keep a few bits of asparagus, & cut up into short bits. The next day strain out the peel, then make a soup base, whisk in an egg, add a few bits of other leftovers, doesn't really matter what. Two meals out of one for little extra effort, & amortize asparagus costs over two meals. Only another day of asparagus smell in the toilet!
