Rinse the white rice thoroughly and cook in 0.5 cup of water until all liquid is absorbed and grains are fluffy.
While the rice is cooking, finely dice the carrots and yellow onion into small, uniform pieces.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat.
Add the diced onion to the skillet and sauté for 3 to 4 minutes until softened and translucent.
Add the ground beef to the skillet, breaking it into small crumbles with a spatula, and cook until fully browned.
Stir in the diced carrots, garlic powder, sea salt, and black pepper until the beef is well-coated.
Pour in the tamari and 0.25 cup of water, then cover the skillet with a tight-fitting lid.
Reduce heat to medium and steam the mixture for 6 to 8 minutes until the carrots are fork-tender.
Remove the lid and stir for 1 additional minute until the remaining liquid reduces into a glossy glaze.
Spoon the savory beef and carrot mixture over the warm rice and serve immediately.
