Hanna's vegetarian tikka masala

I used to make much more vegetarian food before. Can't really remember why I stopped but today I really felt like making something without meat.

Ingredients
1 onion
1 capsicum
1 dl red lentils
1 jar (400 ml) Patak's Tikka Masals sauce
1 cup kale
1 can (400 g) chick-peas
½ head of cauliflower

Chop the onion and capsicum. Rinse the lentils. Fry the onion and capsicum in some vegetable oil and add the lentils. Also add the tikka masala sauce and let it simmer for about 10 minutes. While simmering; grate the cauliflower and place it in a bowl with a lid. Place in the microwave on high heat for about three minutes. Add the chick-peas and the kale to the tikka masala sauce. Let it all get warm and serve together with the cauliflower.
