In a large nonstick skillet over medium-high heat, add the vegan beef and cook until brown, using a wooden spoon to break it up into small chunks.
Once brown and no longer pink, add the sliced onion, soy sauce, brown sugar, agave, sesame oil, garlic, ginger, red chili flakes and black pepper. Stir well into the vegan beef.
Lower the heat to low-medium and continue to cook for 5-10 minutes.
Remove from heat and stir in the sesame seeds.
Serve over rice with chopped green onions and enjoy!
