Heat 1 tbsp olive oil or butter over stove. When heated, add shallot and cook until translucent. Add in garlic and cook until fragrant, roughly 1 minute. Stir in ginger, chopped bell pepper and butternut squash. Let cook for roughly 5 minutes.
Stir in 1 tbsp of red curry paste, turmeric, lemon juice and coconut milk. Let simmer on low, with lid, until squash is soft (roughly 30 minutes). While soup is cooking, cook quinoa in separate pot. Set aside.
Place cashews on pan and roast in oven, under broil, until fragrant (roughly 1-2 minutes, depending on oven).
When soup is done cooking, pour into blender and blend until smooth and creamy. Add back into pot and turn heat on low. Add in shrimp and cook until done, but not overcooked. You do not want the tails to curl! Depending on stove heat, this could be anywhere from 4-8 minutes.
Pour soup into bowls and top with a heaping scoop of quinoa. By packing quinoa tightly into soup ladle or ice cream scoop, you can prepare a nicely rounded heap for dropping quinoa into the center of your bowl. Top with roasted cashews, chopped fresh basil, and red chili flakes. Lastly, drizzle with olive oil and seriously E-N-J-O-Y.
