At the same time, bring a medium sized pot of water to a boil.
Pour in the sauce and reduce the heat to medium. The sauce will quickly begin to thicken and bubble.
Add in the broccoli and bell pepper and fry with the sauce to coat the vegetables and the meat well.
Cover the wok or pan with a lid and let the vegetables continue to cook with the beef and sauce.
Once the water in the pot has a reached a boil, add in the soba noodles and cook according to package instructions.
Reduce the pan with the beef and vegetables to low and add in the chopped orange. Give it another stir to coat the orange with the sauce, and reduce the heat to low.
Once the noodles are done cooking (they take about 3-4 minutes to cook), transfer to a strainer, drain, and rinse with cold water (this will prevent the noodles from overcooking and sticking together).
Divide the noodles between two large bowls, and then top the noodles in each bowl with ½ of the beef and vegetable mixture.
Garnish with a sprinkling of orange zest and roasted sesame seeds over each bowl.
