Heat the vegetable oil in a large skillet over medium-high heat. Add the diced carrots and cook for 3 minutes until they begin to soften.
Stir in the minced garlic and cook for 30 seconds until fragrant.
Add the peas and edamame. Cook for 2 minutes, stirring often, until the vegetables are warmed through.
Push the vegetables to one side of the skillet. Add the cooked rice and break up any clumps with a spatula.
Pour the soy sauce and sesame oil over the rice. Stir everything together and cook for 3 to 4 minutes until the rice is heated and lightly crisped in spots.
Remove the skillet from the heat and stir in most of the sliced scallions. Reserve a few slices for garnish if desired.
