Boil a large pot of water first. Then, heat a tablespoon of sesame oil in a large wok or skillet. Add minced garlic and let it sauté for a few minutes until the garlic starts to turn golden. Add plant-based ground beef of choice and cook it with the garlic according to package directions in a large skillet or wok until browned. Next, add fresh broccoli florets and a teaspoon of rice vinegar. Let this cook, covered if you want the broccoli to soften faster, stirring occasionally, about 5-7 minutes. Then add half of the teriyaki sauce and stir to coat everything in the sauce. Let it cook for another 5 or so minutes while you cook the noodles.
I like my broccoli just slightly crunchy still, not mushy, so cook according to how you prefer the broccoli.

Cook the noodles according to package directions, drain and rinse and then add them to the skillet/wok with the beef and broccoli. Add the remaining half of teriyaki sauce and toss to combine. Let the noodles cook with the beef and broccoli over low heat for another few minutes to really soak up the flavors, then serve into bowls and garnish with sliced green onion and sesame seeds if desired.
