In a large dutch oven over medium heat, warm olive oil and sautee onions until soften. 3-5 minutes.
Add carrots, garlic, ham, split peas and stock. Bring to a boil.
Reduce to a simmer, cover and simmer until split peas are tender. About two hours. Check regularly to ensure soup has not gotten too dry, adding additional liquid if necessary.
Preheat oven to 400 degrees.
Toss peeled and diced sweet potatoes in a large bowl with 1 teaspoon olive oil, 1 teaspoon soy sauce, paprika, garlic powder and onion powder. Toss well and evenly coat the potatoes.
Spread potatoes on a parchment lined rimmed baking sheet and roast at 400 degrees for 20-25 minutes or until the sweet potatoes are completely soft on the inside and caramelized on the outside. Set aside.
Once the split peas are soft, stir in the roasted sweet potatoes. Simmer for a few minutes until the sweet potatoes have warmed through.
Garnish with parsley and sliced onions if desired. Serve.
