After, finely chop artichoke hearts, garlic clove and jalapeno. Then add them into a mixing bowl. Into the same bowl add frozen spinach cream cheese, mozzarella cheese, Parmesan cheese, salt & pepper, to taste. Mix well with a spoon.
Then, using a spatula, evenly spread half of spinach dip mixture, using other two triangles – place them on top of the spinach dip, pinching the middle to combine two puff pastry sheets into one big triangle.
