In a large skillet or wok, heat 2 tablespoons coconut oil over medium-high heat until melted. Add in 1 large red bell pepper, 6 cloves garlic, and 1 small red chili pepper. Cook until veggies are just slightly tender and fragrant, about 3 minutes.
Add in ¼ cup tomato paste, 2-4 tablespoons red curry paste, 1 teaspoon ground turmeric, ½ teaspoon ground cinnamon, and 1 tablespoon sriracha. Stir well and cook over heat for 1-2 minutes to activate the spices.
Add in 1 small pie pumpkin and 14 ounces canned full-fat coconut milk. Bring to a boil, and then reduce heat and simmer until the pumpkin is just fork-tender, but not mushy—about 10 minutes.
Remove from heat. Stir in ⅔ cup unsalted raw cashews, Juice and zest of 1 lime, and ¼ teaspoon sea salt. Serve over top of rice or noodles, and garnish with fresh cilantro and fresh lime wedges before serving.
