Weighing food

I just bought a food scale so I can more accurately know how much food I am eating. What is a good starting point for ounces of veggies and ounces of meat in a salad? Protocol is two salads a day, intermittent fasting with 5-6 hour eating window. Also, some veggies like tomatoes and carrots are a little heavier – do you take that into account when deciding how many total ounces to eat?
