Heat olive oil in a large pot over medium heat. Add the garlic and onions and cook until translucent, about 3 minutes. Add the tomatoes and continue to cook over medium heat until the tomatoes are soft and cooked down, about 5-7 minutes.

Meanwhile, prepare the sauce by blending the soaked cashews, water, apple cider vinegar, smoked paprika, chipotle, salt, and pepper. Blend until fully smooth. Add the blended sauce into the pot along with the spinach and chili flakes. Cook for an additional 3-5 minutes until the sauce is warmed and the spinach is wilted.

Serve over your pasta of choice. I used brown rice linguine.
