Wash sweet potatoes, cut them into halves and place on a baking tray. Brush with a bit of oil, season with salt and pepper then roast in the oven for about 30-40 minutes.
Once cooked, remove and allow to cool a bit. Then gently scoop out the center leaving a medium size layer of flesh inside.
Meanwhile; make the avocado cream.
In a food processor, combine avocado with milk, lime juice, a pinch of salt and pulse until very smooth.
To Finish
Heat a large skillet with 1 tbsp of oil over medium heat and add shrimp, garlic, chilli flakes and a pinch of salt.
Cook the shrimp on both sides until opaque, about 3-4 minutes.
To assemble, place the shrimp in the sweet potato boats, top with avocado cream, garnish with cilantro and serve!
