Heat a large skillet over medium heat for about 2 minutes until hot. Add the ground beef to the skillet, breaking it apart with a spatula as it cooks. Sauté for 5-7 minutes until it’s browned and no longer pink, ensuring the internal temperature reaches 160°F for safety. Drain any excess grease before moving on to the next step.

Add diced vegetables, such as bell peppers and onions, to the skillet with the cooked ground beef. Stir in your preferred spices, like chili powder and cumin, for an extra flavor kick. Continue to cook for about 3-5 minutes, or until the vegetables are tender and fragrant, stirring occasionally to avoid sticking to the pan.

If you're using quinoa, add the rinsed quinoa to the skillet along with the required amount of water or broth. Bring the mixture to a gentle simmer over medium-high heat, then cover the skillet with a lid. Reduce the heat to low and let it cook for about 15 minutes, or until the quinoa is fluffy and has absorbed all the liquid.

Open a can of beans or use pre-cooked beans, then add them directly to the skillet once the quinoa is cooked. Stir well to combine all ingredients, tasting and adjusting seasoning as necessary. Let the stir-fry simmer on low heat for another 2-3 minutes to warm everything through and blend the flavors.

Remove the skillet from the heat and serve the ground beef dinner skillet warm. For added flavor, drizzle optional garlic sauce over the dish or serve it on a bed of fresh salad greens. Enjoy this nutritious and hearty meal that brings the comforting essence of a homemade dinner to your table.
