Heat a large fry pan with a medium heat and add in the olive oil

In the meantime, thinly slice the onion, cut the bell peppers into thin strips and separate the cloves from the head of garlic and cut a slit on each one, leaving the skins on

Add the cut onions, bell peppers and garlic into the hot fry pan, mix together so everything is coated in the olive oil, then mix every 1 to 2 minutes so everything evenly sautes

While the vegetables are cooking, cut the sweet potatoes (skins on) into bite-size pieces that are 2 cm thick (3/4 inch)

After 5 to 6 minutes and the vegetables are lightly sauteed, add in the chopped sweet potatoes, mix together, then mix every 3 to 4 minutes so everything evenly cooks

Once the sweet potatoes are cooked through, about 25 to 30 minutes, season generously with sea salt and just a dash of black pepper, gently mix together, then remove from the heat

Transfer into a large serving dish and garnish with chopped fresh parsley, serve warm or at room temperature, enjoy!
