Preheat oven to 400°F (200°C). Grease a 9x13 baking dish.
In a skillet, sauté shallot in olive oil for 3 mins. Add garlic and red pepper flakes; cook for 1 min.
Stir in tomato paste (1 min), then add cherry tomatoes until they soften.
Add beans, kale, broth, and oregano. Stir until kale begins to wilt.
Transfer to the baking dish. Top with mozzarella and parmesan.
Bake for 20–25 minutes until the cheese is golden and bubbling.
