Beef Noodle Stir Fry

Ever since my friend introduced me to the Japanese udon noodles from Costco (although you can find them in other grocery stores either in the refrigerated noodle section or the vacuum packed type in the Asian foods section), I have been obsessed. I was so excited to see that they carry them here as well. They are so chewy and absolutely delicious when mixed with the perfect sauce. And this right here is the perfect sauce. As soon as I saw the picture for this recipe I knew it had to make its way into my mouth ASAP. And it did not disappoint. And as a bonus, after eating this my three year old told me he liked broccoli. From now on I'm calling this the miracle dish.

2 (7-ounce) packages refrigerated udon noodles (if there is a sauce packet then discard it)
1 tablespoon olive oil
8 ounces beef top sirloin filet, thinly sliced across the grain
1 red pepper, sliced or chopped
1 small broccoli head, florets only
2 carrots, sliced
1 zucchini, sliced

Sauce:

1/3 cup soy sauce
3 tablespoons oyster sauce
1 tablespoon brown sugar, packed
1 tablespoon freshly grated ginger (or 1/2 tablespoon ground ginger)
2 cloves garlic, minced
1 teaspoon sesame oil
1/4 teaspoon crushed red pepper flakes
1/4 teaspoon ground black pepper
Toasted sesame seeds to garnish (optional)

Heat olive oil in a large skillet over med-high heat. Add beef and cook until browned on both sides, about 4-5 minutes per side. Meanwhile, whisk together soy sauce, oyster sauce, brown sugar, ginger, garlic, sesame oil, red pepper flake and ground black pepper in a small bowl then set aside. Boil udon noodles according to package instructions, drain and set aside. When the beef is finished cooking, remove and set aside, drain excess oil but leave some to cook the vegetables in. Add prepared vegetables to the skillet and stir fry until tender, about 5 minutes. Stir in udon noodles, beef and soy sauce mixture until well combined, and heated through, about 2-3 minutes. Serve immediately with a garnish of toasted sesame seeds.
