Thaw a sheet of Trader Joe's Frozen Puff Pastry and cut into 2x2" squares. Press into a mini muffin tin until you have 12-16 spaces filled with pastry.
Roughly chop green beans into ½ pieces and transfer to a bowl. Pour the Trader Joe's Portabella Mushroom Soup over the green beans and mix with a spoon until they're well coated.
Scoop about a tablespoon of the green mixture into each pastry dough lined muffin tin, repeat until all are filled.
Bake the green bean bites in the oven for 20 minutes, until the puff pastry is golden brown.
Remove from oven and top each green bean casserole bite with sprinkle of the Trader Joe's Crispy Fried Onions. Serve warm.
