Squeeze excess water from spinach and tofu. Combine spinach, garlic, onion, and tofu in food processor or blender. Blend until paste-like and mix with rice. Season to taste.
I improvised this recipe when i was looking for something to do with leftover spinach and tofu. I love garlic, so I add a lot, but its good with or without it. This casserole is also very good served cold on a hot summer day!
