Preheat the oven to 400 degrees Fahrenheit
Mix the white wine and milk in a medium sized bowl. Add the bread cubes and soak for 5 to 10 minutes.
Spread half the cubes out on the bottom of the baking dish. Distribute half the pesto and sun dried tomatoes over the bread cubes. Scatter half the cheese over the cubes. Repeat the same process with the remaining bread, pesto, tomatoes and cheese.
Next, whisk the cream, eggs and salt together. Pour over the layered ingredients. Cover the baking dish with foil. Place in the preheated oven and bake covered for 45 minutes. Uncover and continue to bake for an additional 15 minutes until the top layer of cheese is browned. Let rest about 15 minutes before serving.
