Step 1

Preheat the oven to 350ºF.

Step 2

Melt butter in a large skillet. Sauté the onion and white parts of the bok choy until they are just beginning to soften.

Add the garlic, green parts of the bok choy, and spinach. Cook another minute or two longer, until the onions are crisp-tender.

Step 4

In a large mixing bowl, whisk together eggs, milk, and half of the shredded cheese.

Pour vegetables into a round baking dish. Pour eggs over the veggies.

Step 6

Sprinkle with the rest of the cheese and most of the cilantro (reserve some for garnish).

Bake at 350ºF for 30 to 35 minutes, until the eggs are set.

Step 8

Serve with salsa and sour cream.
