Step 1

Heat oil in a large Dutch oven or other heavy pot over medium-high. Add onion and garlic and cook, stirring often, until softened and translucent, about 1 minute. Add scallions, cilantro, and thyme and cook, stirring, 1 minute.

Step 2

Stir in collard greens and spinach just to wilt slightly, then add okra, chopped chile, squash, coconut milk, and 1 tsp. pepper; season with salt. Stir well, then place whole chile on top. Reduce heat to medium-low, cover pot, and simmer until squash is tender and greens are wilted and softened, 40–45 minutes.

Step 3

Remove and discard whole chile (it should be shriveled but still intact). Using an immersion blender, purée Callaloo until smooth. (If you don’t have an immersion blender, blend in batches in a regular blender). The Callaloo should be thick and viscous. Taste and season with more salt and pepper if needed. Serve with rice or baked macaroni pie.
