Drain the cans of tuna into a fine sieve with a bowl underneath, gently flake the tuna to remove any excess oil, roughly chop the onion, roughly chop the garlic and cut the red & green bell peppers into small bite-sized pieces

Heat a stock pot with a medium heat and add in 3 tbsp (45 ml) of the reserved olive oil from the canned tuna

After a couple of minutes add in the chopped vegetables, mix every 1 to 2 minutes so everything evenly sautes, after 4 to 5 minutes and the vegetables are lightly sauteed, add in the vinegar, sweet smoked paprika and hot smoked paprika, quickly mix together, then add in the grated tomatoes, mix together and then simmer

In the meantime, cut the potatoes into small bite-sized pieces that are 1/2 inch thick (1.25 cm)

After 4 to 5 minutes and the grated tomato has slightly thickened, add in the chopped potatoes and season with sea salt & black pepper, mix together, then add in the vegetable broth and bay leaf, turn it up to a high heat and give it a gentle mix

Once it comes to a boil, place a lid on the stock pot and lower to a low-medium heat

After simmering the stew for 20 minutes remove the lid, at this point the potatoes should be cooked through (you can always pierce them with a toothpick to ensure they are done), using a potato masher, gently mash down on the stew to break a couple of the potatoes apart, this is to help thicken the stew, then remove from the heat

Transfer into shallow bowls, top off with some of the reserved canned tuna, black pepper and fresh parsley, enjoy!
