Add 2 tbsp oil to a pan over medium heat and add in shrimp. Then add in 1 tsp paprika, 1 tsp coriander, 1/2 tsp cumin and 1/2 tsp turmeric and saute about 4-5 minutes. Then, spoon shrimp onto a plate and set aside.
Add the remaining oil to the same pan (over medium heat) and also add in the onion. Saute onion for about 5-6 minutes, stirring often.
Add in the garlic and ginger and saute about 2 minutes.
Then add in carrots, celery, and cabbage and sprinkle with the remaining 1 tsp paprika, 1 tsp coriander, 1/2 tsp cumin and 1/2 tsp turmeric, lower heat on stove, and let veggies cook for about 15 minutes covered.
While veggies are cooking, cut up the coconut roti.
Also, chop the green chillies, making sure to get as much of the pith and seeds out if you don't want it too spicy and set aside.
When veggies are ready, add in the shrimp, the cut up coconut roti, green chillies, season with salt and pepper and garnish with chillies and parsley and enjoy warm!
