To cook the lentils:
Put in a saucepan, cover with water. Add salt, 1/2 garlic clove and oil. Bring to a boil, then reduce heat to medium and cook for 20 minutes or until the lentils are tender. Drain and remove the garlic. Set aside.
While the lentils are cooking, heat the olive oil in a large saucepan.
Fry the garlic and the parsley on medium heat until the garlic is golden. Add the chopped onion until the onions become shiny (this means they're cooked but not yet golden).
Add the ground hot pepper and a splash of water. Let it cook for 1 minute. Keep stirring. Add the chopped tomatoes, 1/4 cup of water, salt and pepper.
Cover and cook for 25 minutes at low-medium heat.
Add lentils and mix with sauce.
Simmer for 5-10 minutes.
Serve with white or brown rice and top with 1-2 spoons of sarsa(salsa).
