Quick potato curry

An Indian colleague of mine provided me with the basics for this dish, and it's easily adaptable to personal taste by substituting the veggies.

What you need (2 servings):
450 g potatoes (I use store-bought pre-cooked pommes parisiennes or potato cubes)
100 g frozen peas
1 small onion, halved and cut in strips
1/2 green pepper, finely chopped
1/2 can of tomato cubes, drained
1 tsp garlic paste
1 tsp whole cumin seeds
1 tsp garam massala
1 tsp turmeric
1 tsp sambal oelek (chili paste)
salt & pepper to taste
approx. 100ml cooking cream (suitable for warm dishes)
vegetable oil

Heat some oil in a pan and add the cumin seeds. Once the seeds start to give off scent, add the garam massala and turmeric, onion, garlic, sambal oelek and chopped pepper. Cook for a few minutes until the onion has softened, then add the potatoes. Add the peas and tomatoes after approx. 10 minutes. After another 5 minutes, stir in the cream and season to taste with salt and pepper.
Since the potatoes already provide plenty of carbs, I serve this as a stand-alone dish without rice or naan.

Try these veggie alternatives:
* small cauliflower florets (blanched) - Aloo Gobi is an Indian classic!
* leeks instead of onion
* green beans instead of peas
* red, yellow or orange pepper instead of green pepper, or a combination of different colours
* sliced mushrooms
