In a large skillet, pour in the sesame oil and place over medium heat, allowing the oil to warm up.
Add the minced garlic and grated ginger to the heated oil. Sauté for about 1 minute until fragrant; keep an eye on them to avoid burning.
Raise the heat to medium-high. Introduce the ground beef into the skillet, cooking until fully browned. Use a spatula to break it apart while cooking, which should take about 5-7 minutes.
While the beef browns, take a small bowl and whisk together the soy sauce, honey (or maple syrup), and rice vinegar until smooth.
Once the beef is thoroughly cooked and browned, carefully drain any excess fat from the pan to make the dish lighter.
Toss in the diced bell peppers and broccoli florets. Pour the teriyaki sauce over the mixture and stir everything together. Cook for an additional 3-5 minutes, until the vegetables are tender but maintain a crisp texture.
Remove from heat and let the mixture cool for a few moments in the skillet.
Divide the teriyaki ground beef mixture evenly among meal prep containers, serving it atop a foundation of your choice—either cooked rice or quinoa.
Top each container with the chopped green onions and a sprinkle of sesame seeds for that final touch of flavor and crunch. Seal the containers once garnished.
Notes
