On a baking sheet, toss all of the roasted veggies ingredients together. Bake for 30 minutes.
While the veggies bake, in a large pot over medium heat, add olive oil, garlic, ginger, and a pinch of sea salt. Sauté for 2-3 minutes.
Add the sweet potato and broth. Bring to a boil and reduce to a simmer, cover and cook for 20 minutes or until you can easily poke through the sweet potato with a fork.
Add the roasted veggies to the pot. Stir and cook for 5 more minutes.
Remove from heat. Using an immersion blender or a blender, CAREFULLY blend until smooth.
Stir the cheese in until melted.
Serve topped with toasted pumpkin seeds and an optional additional 1 tsp. drizzle of olive oil.
