Prepare a deep pot. Chop the onion and add it to the pot.
Cut the carrot into sticks.
Cut half a tomato into small cubes.
Cut half of the bell pepper into small cubes.
Pour oil into a pot and sauté the vegetables over low heat for a few minutes, until softened.
Wash the rice in several changes of water until the last water runs clear, about 7-8 washes. Add the rice to the vegetables in the pot.
Pour in enough water to cover the rice and about 3 cm above the rice. Sprinkle with salt to taste, and if desired, add peppercorns and ground thyme. First boil over high heat until the water begins to boil, then reduce the heat to low and cook for 20 minutes.
The healthy vegetable pilaf is ready. Enjoy your meal!
