Preheat oven to 400 degrees Fahrenheit.

Heat oil in large frying pan over medium-high heat. Add beans and tomatoes and cook for a two to three minutes, add seasoning and continue to cook for another few minutes. Add salt and pepper to taste (**if you use unsalted beans, you will more likely have to add salt).

Use a three and a half- to four-inch round cookie cutter to cut puff pastry squares into circles. Spoon one and a half tablespoons of the bean mixture in center of puff pastry rounds and top with some grated cheese. Fold to form Hamantaschen.

Brush with egg or melted butter. Top with additional grated cheese.

Bake for about 20 minutes, until puff pastry is nice and golden.

In the meantime, make salsa, by mixing together all ingredients.

Top Hamantaschen with salsa and enjoy!
