Preheat a skillet over medium heat.
Add the oil and sauté the onions and red bell pepper until wilted, around 5 minutes.
Add the tomatoes, season with salt a red pepper flakes, stir and cook for 5 more minutes, stirring occasionally.
With a wooden spoon, create 4 nests in the sofrito. Crack the eggs individually and carefully place them in each nest. Cook undisturbed until the eggs are done (I like mine soft).
Sprinkle with parsley.
In the meantime, heat the tortillas in a pan over medium heat, 30-45 seconds per side.
Serve and egg with sofrito over each tortilla and eat inmediately.
