Drain the soaked chickpeas and rinse them thoroughly under cold water.
Heat the olive oil in a large pot over medium heat, and add the finely chopped onion. Sauté until it becomes translucent and fragrant, about 5 minutes, with a gentle sizzle and a sweet aroma filling the air.
Add the minced garlic to the onions and cook for another minute until fragrant, hearing a soft crackle and smelling toasted garlic.
Stir in the ground cumin and smoked paprika, allowing the spices to toast slightly and release their warm, smoky aroma for about 30 seconds.
Add the chopped tomatoes to the pot, stirring to combine. Let them simmer for 5 minutes until they break down and the mixture thickens slightly, with a vibrant red color and fragrant scent.
Pour in the vegetable broth and add the rinsed chickpeas. Bring the mixture to a gentle boil, then reduce the heat to low to maintain a steady simmer. Cover partially and cook for about 45 minutes, until the chickpeas are tender and the stew thickens, producing a comforting bubbling sound.
Uncover the pot and stir in the chopped greens. Cook for an additional 5 minutes until wilted and vibrant, with the greens adding freshness and color to the thickened broth.
Taste the stew and adjust seasoning with salt or lemon juice if needed, enhancing the overall flavor profile and brightness of the dish.
Serve the hot chickpea stew in bowls, enjoying its hearty texture and rich, smoky aroma with crusty bread or rice if desired. The thick, tender beans and vibrant greens make for a filling, comforting meal.
