Start by washing and chopping all vegetables: broccoli, red bell pepper, zucchini, and mushrooms; set them aside. Mince several cloves of fresh garlic to enhance the flavor. Measure out soy sauce, chili flakes, and brown sugar for the ground beef.

In a large skillet, heat 1 tablespoon of sesame oil over medium heat. Once shimmering, add the minced garlic and sauté for about 30 seconds until fragrant. Add the ground beef, breaking it apart as it cooks. Stir until browned and crumbly, roughly 5-6 minutes. Mix in soy sauce, chili flakes, and brown sugar, cooking for another 3-4 minutes until the sauce thickens slightly, then remove from heat.

In another pan, heat 1 tablespoon of olive oil over medium-high heat. Add minced garlic and sauté for 30 seconds until lightly golden. Toss in the mushrooms first, stirring for about 2 minutes until they soften. Next, add the zucchini, red bell pepper, and broccoli. Stir-fry for about 4-5 minutes, or until vegetables are tender-crisp. Splash in a bit of soy sauce, and toss to ensure all veggies are nicely coated.

To serve your delicious Spicy Ground Beef Stir-Fry Bowl, spoon a generous helping of steamed white rice into each serving bowl. Top the rice with the sautéed beef, ensuring the rich flavors blend together. Add a colorful mix of garlic veggies on the side or on top to create a visually appealing dish. Consider drizzling any leftover sauce from the beef for an extra burst of flavor.
