Begin by washing and chopping the zucchini into even-sized pieces to ensure uniform cooking. Next, measure out your ground beef, rice, and spices. Having all your ingredients ready will streamline your cooking process.

In a medium pot, combine your rice with water according to the package instructions, bringing it to a boil over high heat. Once boiling, reduce the heat to low, cover, and let it simmer for about 15 minutes.

While the rice cooks, heat 1 tablespoon of olive oil in a large skillet over medium heat. Once the oil is shimmering, add the chopped zucchini. Sauté for about 5 minutes until the zucchini is tender.

To the skillet with the sautéed zucchini, add the measured ground beef. Use a wooden spoon to break it apart as it cooks, allowing it to brown for about 8-10 minutes.

Once the beef is browned, sprinkle in the salt, pepper, and oregano. Stir well to incorporate the spices, cooking for another 2-3 minutes.

To serve, place a scoop of fluffy rice into bowls. Top the rice with the savory beef and zucchini mixture, and squeeze fresh lemon juice over the top.
