In a saucepan, heat the olive oil over medium heat.
Add chopped onion and sauté until translucent. Sprinkle salt over the onions and stir.
Add cumin powder, curry powder, and chopped garlic. Stir well to combine.
Add the cubed sweet potato and cook for a few minutes until slightly softened.
Crumble the vegetable stock cube into the saucepan and stir.
Add the red cracked lentils and water to the saucepan. Stir to combine all ingredients.
Bring the mixture to a boil, then reduce the heat to low and simmer for about 20 minutes or until the lentils and sweet potatoes are very well cooked, stirring occasionally.
Use a hand blender to blend the soup to a smoother consistency, if desired.
Serve the red lentil soup hot, either on its own or accompanied by toasted bread.
