Savory Greens Stir Fry

1 tablespoon olive oil
1 clove garlic, minced
1 small onion, halved and sliced thin
1 can (7 ounce) water chestnuts, drained and thinly sliced
3 shiitake mushrooms, sliced
1 bunch greens (kale, broccoli raab, or mustard greens)
1 teaspoon mirin
1 teaspoon tamari (or soy sauce)
freshly ground black pepper, to taste

Heat the oil in a large skillet over medium high heat. Add the garlic and onions and sauté until onions are translucent. Be careful not to brown the garlic or it will give a bitter taste.

Add the water chestnuts and shiitake mushrooms. Sauté for 3 minutes. Add the greens and sauté for 1 minute. Add the mirin, tamari and pepper and sauté until the greens are tender.
