Prepare the chicken. Remove the skin from the drumsticks, thighs and breast. Trim off most of the excess fat. Cut the breast into about three or four medium sized pieces. Dice the onions, the tomato and the pepper.
Heat the oil over medium heat in a large heavy-bottomed pot, add the onions, and sauté it on low to medium heat until they are golden and tender.
Remove the pot from the heat, and add the sweet Hungarian paprika. I use 2 tbsp paprika, for the colour and flavour, but if it is too much for you, add a bit less at the beginning, and more later as you like.
Place the pot back to the heat, and add the chicken. Carefully, on medium heat sear the chicken for a couple of minutes, but stir frequently to avoid burning the paprika. Searing the meat helps to keep the flavours inside.
Add the diced tomato, diced pepper, the salt and ground black pepper, and stir. I used 1 tsp salt in the entire recipe, but you could start with about half of the amount, and add more towards the end as you wish.
Reduce the heat to low, cover and let it simmer for about 1-1.5 hours. You can add 1 or two tbsp water if you want at this point, but you will see, the chicken-tomato-pepper mixture will start releasing a lot of liquid very soon. Every 15-20 minutes gently stir and later, once there is enough liquid, just shake the pot horizontally left and right. The meat will turn very tender, so by shaking the pot rather than stirring you can avoid "destroying the meat"
Serve it with some egg noodles or dumplings, and with some delicious pickles on the side. Bon appétit! Jó étvágyat!
