Brownie Banana Split Pizza

In a bowl prepare brownie mix according to package directions. Pour the batter into a greased deep-dish pizza pan with high sides. Bake at 350°F (175°C) for 15 to 20 minutes ,or until set. Cool. Meanwhile, in a small bowl, beat cream cheese with an electric mixer on medium speed until fluffy. Gradually beat in sweetened condensed milk, frozen concentrated orange juice (thawed), and vanilla. Chill before spooning over the brownie crust. Slice bananas and dip in lemon juice. Arrange on the cream cheese frosting. Add sliced strawberries and chopped nuts on top. In a small saucepan melt semi-sweet baking chocolate and butter. Drizzle over the top. Chill for about 1 hour.
