Peel and chop onions and garlic and sauté in oil. Add the red lentils. Sweat the curry and tomato paste. Deglaze with the broth, bring to the boil and simmer on a low heat for 20 minutes.
Season to taste with salt and pepper. When it comes to lenses, it is up to you how you want them. I personally like it a little bit firm to the bite.
While the lentils are cooking, cook the spaghetti in salted water according to the package instructions. Serve both together.
My tip: With 2 teaspoons of Garam Masala it is particularly delicious!
