Indian curry vegetables

I love Indian food, since we moved to Belgium, we couldn't find any Indian restaurant :( BUT.... we have Indian friends! yay! Every time they make curry, I always eat twice more than usual... So I asked for the recipe so that I need not to wait for gatherings to taste the curry :)

Regarding vegetables, you can use whatever vegetables that you like... but the MUST ingredients are onion and tomatoes in this recipe. 
The most important thing is that the seasoning, if you use certain seasoning, you can't make good curry.

Ingredients (3-4 person)
1 onion
3 medium size carrots
100g haricot
100g broccoli
200g mushroom
3-4 tomatoes

Optional: potato, green pepper, cauliflower... Be creative!

Seasoning
2tsp coriander powder (I like using coriander seeds)
1/2tsp tumeric powder
1tsp chilly powder
1/2tsp garam masala

1 can coconut milk

Instructions
1. In a big pot, at medium fire, fry coriander seeds with oil and onion
Note: if you use coriander powder, you can add later with all seasonings...

2. When you smell the flavor coming out, add carrots, haricot and broccoli & all the seasoning EXCEPT coconut milk, stir well

Cover the lid and let it cook until the veggies become soft - use a fork and pinch in the carrots to test if it is soft

3. Add in mushroom and coconut milk, stir well, let it cook until the coconut milk boils

4. When the milk starts boiling, add in tomatoes, cook for 5 mins and turn off the heat

Serve hot with rice or naan!
Enjoy!
