In a pan over medium heat, add the oil, the onion and sauté until lightly browned, add the garlic and sauté again until browned.
Add the diced chicken, the salt, the black pepper, the oregano and the sweet paprika, mix it all together for 1 minute, cover the pan and let it cook until all the water in the chicken has dried.
Add the tomato, stir for 1 minute, cover the pan and cook until the tomato breaks down, the water dries up and the spices give our chicken some color.
Add the ketchup and the mustard, stir for 1 minute and turn off the heat.
Add the table cream - it is important that the heat is turned off to keep the table cream from curdling. Mix it all together very well and serve with some white rice and shoestring fries.
