Heat the oil in a saucepan over medium heat and cook the onion until soft.
Add the garlic and cook for about 30 seconds.
Add the diced chicken and cook until it changes colour.
Stir in the tomato purée and both types of paprika, coating the chicken well.
Add the stock, carrot, and red pepper. Simmer for about 20–25 minutes, until the sauce has thickened and the chicken is cooked through.
Add the peas, cover, and cook for another 5 minutes.
Turn off the heat, stir in the parsley, and season to taste.
Serve warm with your choice of potatoes, pasta, or dumplings, and gherkins on the side.
