Just onions and garlic fried in a pot, then adding beef/chicken strips cut into little cubes, one hell of a lot of red (european, not asian there's a big difference in taste and texture) paprika powder, a tiny bit of water, lower heat, stir once in a while, add more paprika powder, and if you can get your hands on it some eros pista at the end (otherwise just a chili paste of your prefered strength , but not vinegar-ish, no tabasco and such) and boom splurge a little more water in to get the thickness/liquidness you want and either eat it like that with a spoon or pour it on pasta or rice.
If you went with chicken (or the vegetarian way with mushrooms) you should add a bit of sour cream/creme fraiche (but you need to put that in a little bowl, add spoonfuls of the sauce to the bowl slowly while stirring to equalize the temperature before adding it to the sauce, so the creme fraiche doesn't part and turn ugly)
