5. Portion of Duck (50 grams): 61 calories

Total Breakfast Calories: 702 calories

Nutritional Breakdown:

If necessary, you may adjust the portion sizes of the individual food items to fine-tune the calorie count. For instance, reducing the amount of avocado or increasing the portion of grilled chicken can adjust the caloric intake.
