Heat oil in large nonstick skillet over medium-high heat until hot.
Add half of the beef and 1 teaspoon of garlic to the skillet.
Stir-fry beef 2 to 3 minutes or until outside surface is no longer pink and minimum temperature reaches 145°F. Remove beef from the skillet and set aside. Repeat with remaining beef and garlic.
Add vegetables to the same skillet. Cook and stir frequently until heated through and tender, about 5-7 minutes.
Return beef to the skillet, stirring occasionally until heated through; about 3 minutes. Reduce heat to low.
In a small saucepan, whisk honey, soy sauce, sesame oil, ginger, garlic and crushed red pepper flakes. Bring to a boil over medium-low heat and simmer 3-5 minutes. Set aside.
Add hot cooked noodles and sauce to the skillet, gently tossing to coat with beef, vegetables and sauce.
Garnish with sesame seeds, if desired.
