Preheat oven to broil on high and position rack in the upper third of the oven.
Drain and rinse beans in a colander; set aside to drain further.
4 (15 oz) cans cannellini (white kidney) beans
Wash and dry kale. Fold leaves in half lengthwise, slice off stems, and finely chop leaves.
1 bunch kale
Peel and thinly slice garlic.
6 cloves garlic
Preheat a large ovenproof skillet over medium heat.
Grate cheese and set aside.
½ (8 oz) block mozzarella cheese
Once the skillet is hot, add oil and swirl to coat the bottom. Add garlic and tomato paste; stir to combine.
2 tbsp extra virgin olive oil
4 tbsp tomato paste
Add kale to the skillet in handfuls, waiting for the kale to wilt slightly before adding the next handful; cook, stirring often, until kale softens, 4-5 minutes.
Add beans, hot water (from the tap), and spices to the skillet; stir to combine. Bring to a boil, then sprinkle with cheese and place in the oven; broil until cheese has melted and is browned in spots, about 4 minutes. Remove from the oven.
1 cup water
1 tsp salt
½ tsp black pepper
½ tsp Italian seasoning
½ tsp onion powder
Meanwhile, cut bread slices on the diagonal and place on a baking sheet pan in a single layer; drizzle with oil on both sides.
4 slices whole grain bread
2 tsp extra virgin olive oil
Place bread in the oven and broil, flipping halfway through, until nicely toasted, 2-3 minutes. Remove from the oven.
Divide white bean mixture between plates or bowls. Serve with toast for dipping. Enjoy!
