Preheat the oven to 350°F. While the oven is heating, prep ingredients.
Prep the bruschetta ingredients per instruction above.
Place sliced bread on a baking sheet and bake in the oven until golden brown.
Mix together the tomatoes, onion, garlic, vinegar, basil, and olive oil in a bowl and season with salt and pepper to taste. Refrigerate until ready to serve.
Optional: Heat a nonstick pan on medium heat. Once hot add the oil. Cook the chicken on both sides until nicely brown to an internal temperature of 160 degrees using a thermometer. Set aside for 2 to 3 minutes then dice into bite sized pieces.
Add the leftover fettuccini and milk to a saute pan over medium low heat. Stir occasionally, until the sauce is creamy and hot. Mix in the chicken (if using).
Serve: Spoon the bruschetta mixture onto the bread. Enjoy with the fettuccine and lemonade.
