Soy sauce, butter, and milk go well together. A nutritious and delicious dish!
We never lack for milk in my house. I use it in cooking and in baked goods. Anything goes well with milk, and so this time I mixed it with soy sauce and butter.
If you're not a fan of spicy dishes, or if cooking for children, adjust the amount of red chili pepper. In place of onion, you can use asparagus, broccoli, or spinach, and it will still be delicious.
