Chop the red onion and fry it in a pan over high heat with a bit of butter.

When the onion becomes translucent, add the ground beef and continue stirring.

Meanwhile, cook the rice according to the instructions.

Dice the tomato and parsley, then mix them together.

Assemble your bowl with all these ingredients and add half an avocado.

Top with yogurt and, if desired, hot sauce before serving.
