Heat the olive oil in a medium skillet over medium heat.
Add the diced yellow onion and red bell pepper to the skillet, sautéing until the vegetables are softened and translucent.
Stir in the minced garlic, smoked paprika, and ground cumin, cooking for 1 minute until highly fragrant.
Pour in the tomato puree and bring the mixture to a gentle simmer.
Cut the chicken breast into bite-sized pieces and add them to the simmering sauce, cooking for 8-10 minutes until the chicken is opaque and tender.
While the stew simmers, place the egg in a small pot of boiling water for 6 minutes, then transfer to an ice bath, peel, and slice in half.
Season the stew with sea salt and black pepper to balance the flavors.
Ladle the chicken stew into a bowl, top with the halved soft-boiled egg, and garnish with freshly chopped parsley.
