Prep your base: Cook cauliflower rice or brown rice according to package directions. Keep warm.
Mix the sauce: In a small bowl, combine low-sodium soy sauce, a small spoon of gochujang, a splash of rice vinegar, a drizzle of sesame oil, and a teaspoon or two of brown sugar or honey. Add red pepper flakes if desired.
Taste and adjust for sweetness, salt, and heat.
Warm the pan: Heat a large nonstick skillet over medium-high. Lightly mist with oil spray.
Cook the aromatics: Add diced onion. Sauté 3–4 minutes until softened.
Add garlic and ginger; cook 30–60 seconds until fragrant.
Brown the beef: Add the lean ground beef. Break it up with a spatula and cook until fully browned, about 5–7 minutes. If any liquid accumulates, cook it off to concentrate flavor.
Optional: Add veggies: Stir in thinly sliced carrots, broccoli, or snap peas.
Sauté 2–3 minutes until crisp-tender.
Sauce it up: Pour the sauce over the beef. Stir and simmer 1–2 minutes until glossy and slightly reduced. It should cling to the meat without pooling.
Finish: Turn off heat.
Stir in sliced green onions, reserving some for topping. Taste and adjust seasoning—more soy for salt, vinegar for brightness, or gochujang for heat.
Serve: Spoon over your base. Garnish with extra green onions and sesame seeds.
Add a light drizzle of sesame oil if you didn’t use much earlier.
