Preheat the oven to 350F and line a 9"x 13" pan with tin foil, leaving enough overhang that you can lift out the cake once it is cooked.

Melt the butter (about 30 seconds on high in the microwave). Put the cookies, walnuts, and salt into a food processor and pulse until broken down into crumbs. Add the melted butter and pulse until combined. Spray the pan with some non stick spray, and spread the crumb mixture along the bottom, flattening it with your hands.

In a large mixing bowl, add the cream cheese, sugar, sour cream, and vanilla, and mix until smooth. Add the eggs one at a time, mixing until incorporated. You don;t need to over mix, you just want a smooth consistency.

Pour the mixture into the pan and smooth with a spatula. Put it in the oven for 30 minutes, then turn it down to 300 and cook for another 20 minutes. Turn off the oven, open the door, and let it sit in the oven for another 15 minutes. Let it cool on the counter until you can handle the pan, then put it in the refrigerator for 2 hours to help it set up.

There are a lot of cooking techniques like placing the pan in water while it cooks to try to keep the top from cracking. But since we are going to top the cheesecake with strawberries, you don't have to worry about cracks!

Take the cheesecake out of the refrigerator and use the foil overhangs to lift it out of the pan. Cut the strawberries in vertical slices, and place them on the top of the cake like scales.

Cut the cake into 3"x 2" squares, then pipe some Nutella stripes across the top. I put the Nutella in a Ziplock bag that I cut a tiny corner off of to pipe.
