Preheat your oven to 375°F (190°C). Unroll the crescent roll dough and press it firmly onto the bottom and about 1/2 inch up the sides of a lightly greased 13x9-inch baking dish. Be sure to press and seal all the perforations to create a solid crust.
Bake for 8 to 10 minutes, or until the crust is a beautiful light golden brown.
Let it cool completely on a wire rack.
While the crust cools, prepare the creamy spread.
In a medium bowl, combine the softened cream cheese, mayonnaise, sliced green onion, and dried dill.
Mix until everything is smooth and well-combined.
Once the crust is completely cool, carefully spread the cream cheese mixture in an even layer over the top.
Sprinkle evenly with the shredded lettuce, sliced olives, chopped sweet pepper, and cucumber.
Finish by topping with the crumbled feta cheese and chopped tomato.
Cover the dish with plastic wrap and chill in the refrigerator for at least 2 to 4 hours. This allows the flavors to meld together beautifully.
When ready to serve, cut into squares and enjoy!
