To make the taco seasoned potato cubes, preheat oven to 400F/200C and line a large baking tray with parchment paper. Steam the potato cubes for 10-15 minutes, until almost tender. Remove and place in a bowl. Add the spices and sea salt and toss until evenly coated. Spread the potatoes evenly onto the baking tray and bake for 20-25 minutes, stirring half way, until browned and crispy.
To make the cheese sauce, steam the diced potatoes and carrot over boiling water for 10-12 minutes or until tender. Place in a blender together with the lime juice, onion powder, garlic powder, and paprika. Blend until smooth.
To make the salsa, combine all the ingredients in a medium-sized bowl and mix well. Set aside.
Divide the seasoned potato cubes, salsa, cilantro, hot peppers, and nacho cheese sauce between serving bowls. Serve immediately.
