Breakfast Casserole Serving Size and Nutrition

This casserole deceptively low calorie but nutritionally dense with micro and macronutrients. The entire dish looks like it should feed 9 based on aesthetic serving size, but then it would be too low calorie to serve as a meal. The entire dish, with the recipe as listed is only 4 servings. Get ready to be very, very full! Based on 4 servings, you can count on:

  • 250 calories
  • 3g fiber
  • 16g protein
  • 96% vitamin C
  • 45% vitamin A
  • 28% calcium
  • 11% iron

The dish is also high in phosphorus and selenium. FYI, I just read about a study from Diabetes Care the other day while working on my CPT recertification, that people with high levels of selenium were less likely to develop type 2 diabetes.

Might you make this breakfast casserole some day?

If so, which of your favorite veggies might you toss in there?
