Boil a large pot of water over high heat. Add udon noodles and cook according to package instructions, about 8-10 minutes. Drain and rinse under cold water.

In a large skillet, heat oil over medium-high heat until hot.

Add minced garlic and ginger, stirring for about 30 seconds until fragrant.

Add your chosen protein and cook for 4-5 minutes until fully cooked and golden brown.

Toss in fresh vegetables and stir-fry for 2-3 minutes, until vibrant and tender but still crisp.

Add the drained udon noodles and toss everything together, stir-frying for an additional 2 minutes.

Pour in soy sauce, oyster sauce, mirin, and sesame oil. Stir well and cook for another minute.

Serve immediately, optionally garnishing with sesame oil.
