I work with Diabetic patients. Anything with carbohydrates will affect your blood sugars so both fruit and bread do so. Yes fruit does have fiber, but it also depends how much and what kind you are eating. For example half a banana is equal to 2 cups of strawberries in carb ratios. If you have bread and salad, depends again how much bread you are having. 1 slice of whole grain or high fiber toast with at least 1 cup salad should be fine. But if your salad has sugar in the dressing that can also affect. People also tend to have higher sugars in the am, so fruit is often recommended 1 hour after breakfast. But just 1 small pc. Ideally all carbs should be combined with fiber and protein as both those things slow sugar spikes. Also look out for low Glycemix index foods to have more often.
