Boiled eggs plus fruit is the simplest low calorie lunch box that actually keeps you stable through the afternoon. Protein, fiber, no crash.
Place eggs in a pot and cover with cold water by 1 inch. Bring to a boil over medium-high heat.
Once boiling, reduce the heat to low and simmer for exactly 10 minutes for fully cooked yolks.
While the eggs cook, wash the apple, banana, blueberries, and baby spinach thoroughly under running water.
Slice the apple and banana into bite-sized pieces, and pat spinach dry with a paper towel.
Cool the eggs in an ice water bath, peel, and season with salt and black pepper.
Combine spinach, apple, banana, and blueberries in a lunch box. Drizzle with lemon juice to prevent browning and add brightness.
Arrange the peeled boiled eggs alongside the fruit and salad mix for balanced presentation and easy packing.
