Preheat your oven to 400°F (200°C) and prepare a baking dish with parchment paper.

In a large mixing bowl, combine drained butter beans with olive oil, minced garlic, salt and pepper. Mix well.

Fold in chopped sun-dried tomatoes, fresh spinach, and crumbled feta cheese until well combined.

Sprinkle in oregano, basil, and red pepper flakes. Stir to infuse the mixture with flavors.

Spread the butter bean mixture evenly in the prepared baking dish and press down lightly.

Bake in the preheated oven for 25-30 minutes or until golden brown and bubbling.

Allow to cool for a few minutes and serve warm, garnished with fresh herbs.
