1 tablespoon butter
1 small onion, finely chopped
2 cloves garlic, minced
2 heads broccoli (or about 3 cups broccoli rice), run through the food processor to "rice"
1 cup sharp cheddar cheese
1/2 cup mozzarella cheese
1/4 cup freshly ground black pepper
Heat the butter in a pan. Add the onion and cook until just tender, about 4 minutes, then add the garlic and cook until fragrant, 1 minute more.
Add the broccoli rice to the pan. Stir well to combine. Cook, stirring frequently, until the broccoli rice is tender, about 7-10 minutes.
When the broccoli rice is tender, add the shredded cheese. Stir to combine and to allow the cheese to melt, pulling the pan from the heat if needed to keep the cheese from burning. Season with black pepper and serve.
