Preheat the oven to 375 degrees F (190 degrees C). Line a baking sheet with parchment paper or a silicone baking mat.
Mix spinach, artichoke hearts, cream cheese, mayonnaise, feta cheese, Parmesan cheese, and garlic together in a large bowl; season with salt and pepper.
Remove rolls from each can and separate into 8 triangles for a total of 24. Place a heaping tablespoon spinach-cream cheese mixture on the wide end of each triangle. Roll up each triangle, starting at the wide end; fold the ends underneath and dredge in bread crumbs to coat. Place seam-side down on the prepared baking sheet.
Bake in the preheated oven until golden brown, 10 to 12 minutes. Serve hot.
