In a large skillet over medium heat, heat the olive oil.

Sauté the red peppers, carrots, garlic, bell pepper, and onion for 5 to 7 minutes.

When everything is slightly browned, raise the heat to medium-high and add the ground beef.

Cook for 5 to 7 more minutes, or until browned.

Add the tomato paste and red pepper flakes, season with salt and pepper, and stir until everything is incorporated.

Keep warm over low heat until ready to serve. Scoop into bowls, and sprinkle with the scallions.
