(I suggest adding corn and green beans, why not!)
1 large onion, coarsely chopped
1-2 fresh tomatoes (sun-dried work just as well)
6 tablespoons extra-virgin olive oil, divided
4 garlic cloves, minced
1/2 teaspoon sweet smoked paprika (pimentón dulce)
2 (19-ounces cans) cannellini beans, rinsed and drained
1 cup water
1/2 -3/4 lb Spinach, tough stems removed
Cook onion and sun-dried tomatoes in 4 tablespoons oil with 1/2 teaspoon each of salt and pepper in a 5- to 6-qt pot over medium heat, stirring occasionally, until onion is browned, 6 to 8 minutes. Add garlic and paprika and cook, stirring, 1 minute.
Stir in beans, water, spinach, and 1/2 teaspoon salt and cook, covered, stirring occasionally, until spinach is wilted, about 5 minutes. Season with pepper and drizzle with remaining 2 tablespoons oil.
