Combine the ground beef with oats, an egg, and your preferred seasonings, then shape the mixture into small meatballs.

Heat a pan and fry the meatballs, turning them occasionally. Add chopped peppers, spring onions, and tomatoes, and let everything cook together for a while on medium heat.

Meanwhile, prepare your choice of rice. Once cooked, divide the meatballs and rice to your bowls or container, store them in the fridge for meal prep, and enjoy!
