Heat oven to 475º F. In a 10-inch ovenproof skillet, heat the olive oil over medium-high. Fry the garlic until it’s lightly golden, about 1 minute. Stir in the tomato paste and fry for 30 seconds, reducing the heat as needed to prevent the garlic from burning.

Add the beans, water, and a large pinch of kosher salt and pepper and stir to combine. 

Sprinkle the cheese evenly over the top, then bake until the cheese has melted and browned in spots, 5 to 10 minutes. If the top is not as toasted as you’d like, run the skillet under the broiler for a minute or 2. Serve with toasted baguette slices.
