In sauté pan or wok, heat sesame oil on medium-low heat. Add garlic and cook until fragrant. Turn heat up to medium-high and add steak. Cook until meat begins to brown and pink begins to disappear. Drain off any excess fat.
Add carrot and onion, cook until both just begin to soften. Add soy sauce (or tamari), honey, and red pepper flakes to mix. Reduce heat to medium-low and simmer until sauce thickens.
Spoon over brown rice or quinoa. Top with scallions and fresh cilantro to serve.
