Cook the rice: Prepare 1.5 cups dry rice to yield about 3 cups cooked. Fluff and let it steam off so it doesn’t turn gummy in the containers.
Prep the veggies: Thinly slice cucumbers and cabbage, and shred carrots.
Toss cucumbers with a squeeze of lime, a pinch of sugar, and salt for a fast, bright crunch.
Make the sauce: In a bowl, whisk soy sauce, brown sugar, rice vinegar, sesame oil, and gochujang or red pepper flakes if using. Set aside.
Sauté aromatics: Heat oil in a large skillet over medium-high. Add garlic and ginger, stirring 30 seconds until fragrant.
Don’t let them brown.
Brown the beef: Add ground beef, breaking it up with a spatula. Cook 5–7 minutes until no pink remains and edges get a bit crispy. Drain excess fat if needed.
Sauce it up: Pour the sauce into the skillet.
Stir until the beef is evenly coated and glossy, about 2 minutes. Taste and adjust salt, sweetness, or heat.
Finish with garnish: Stir in half the green onions. Sprinkle in sesame seeds and remove from heat.
Assemble bowls: Divide rice among 4–5 meal prep containers.
Top with the Korean-style beef, then add carrots, cucumbers, and cabbage on the side to keep them crisp.
Optional drizzle: Mix 1 tablespoon lime juice with 1 teaspoon soy sauce and a small dollop of gochujang. Drizzle over the veggies or pack on the side.
Cool and store: Let containers cool uncovered for 15–20 minutes before sealing to prevent condensation.
