Preheat the oven to 400 degrees.
Spray down a baking sheet and place the cherry tomatoes on it. Spray the tops of the tomato with your oil spray (very lightly!)
Roast in the oven for 20 minutes.
While cooking, whisk together the egg and milk.
Sprinkle in a dash of salt, pepper, and Italian seasoning. Whisk to combine.
Heat up a skillet over medium-low heat. Melt the butter in the pan, making sure the bottom is fully coated.
Dip the bread in the egg mixture, making sure both sides are soaked. Place on the pan. Repeat for each slice of bread, that can fit on the pan.
Flip when the bottoms of the toast get golden brown, about 2 to 3 minutes.
Serve with roasted cherry tomatoes on top, sprinkled with grated parmesan cheese.
