1. First things first, measure out 1 1/2 cups of red lentils and 1/2 cup rice. Dump these into a bowl and fill it up with warmish water. Allow the lentils to soak while you continue on with the next couple of steps.
2. Grab a generous enough sized pot. Let 1 1/2 tbsp of oil heat up as you chop your onion and garlic.
3. Now that your oil has heated, dump your garlic and onion into the pot. Sautee these until they are nice and tender, about 10 minutes. Make sure to add a dash of salt to this to help speed up the process.
4. When your onions and garlic are cooked down and nice and tender, strain your lentils and rice. Dump this mixture into the pot and add a little water. Give it a good stir, put the lid on, and leave for at least twenty minutes.
5. Add some tomatoes and paste
6. After twenty minutes has passed, dump 1 tbsp of ground cumin and 1 tbsp of stock powder into the mix. Stir. Let it cook with the lid off for another five to ten minutes, depending on how things are looking (and tasting).
7. After five to ten minutes, check to see if your mix needs more cumin or stock powder. Stir in if this is the case.
