In a deep, wide skillet or Dutch oven, heat the oil over medium. Add the tomato paste and garlic. Stir constantly for 30 seconds, breaking up the paste.
Stir in the sun-dried tomatoes, Cajun seasoning, Italian seasoning, and salt.
Stir in the chickpeas and coconut milk. Bring to a simmer.
Let simmer gently for 4 minutes, stirring periodically and adjusting the heat as needed. The coconut milk should thicken but still be saucy. Stir in the spinach a small handful at a time, allowing it to wilt.
Sprinkle with fresh basil. Taste and adjust seasoning as desired (I added a pinch of additional salt). Serve warm with rice or naan.
