In a medium saucepan, heat the olive oil over medium heat for about 1 minute.
Add the minced garlic and sauté for 1-2 minutes until fragrant, being careful not to burn it.
Stir in the uncooked brown rice, coating it in the olive oil and garlic mixture, and sauté for an additional 2-3 minutes.
Pour in the tomato sauce and vegetable broth, stirring to combine all ingredients.
Add the ground cumin and mix until evenly distributed.
Bring the mixture to a boil, then reduce heat to low and cover the saucepan.
Allow the rice to simmer for 45-50 minutes or until tender and liquid is absorbed.
Remove from heat and let sit covered for an additional 10 minutes, then fluff with a fork and serve warm.
