I've been throwing together some pretty fast, yet satisfying meals lately. This one may have taken 5 minutes of my time.
Miso Soup with Collards, Broccoli and Leeks, + Crunchy Nori Garnish
Get a little water boiling. Toss in fresh collards (i chiffonade them, really small), broccoli, and leeks. Simmer until just tender. Remove from heat and stir in a tablespoon or so of miso paste until dissolved. Garnish with toasted seaweed crumbles (you can get these in the Asian section at Whole Foods; they're often toasted with sesame seeds, salt, and sugar - they add a nice crunch).
