This is a great side dish for fish (sesame crusted tuna or salmon).
To add veggie protein: use edamame instead of peas, or baked tofu.
If you skip the cheese: add toasted sesame seeds and diced avocado
To make this gluten free, use 100% buckwheat soba noodles or brown rice noodles. My favorite brand right now is King Soba
because the texture of their noodles is perfect. Also, be sure to use tamari and not soy sauce.
