Mash black beans with salsa, spread on bread, layer sliced avocado on top
Almond butter with fresh blueberries in a sandwich or open face
Baguette with pesto, bell peppers, tomatoes, warmed in air fryer and wrapped in foil
These are our favorite. My kids like to make egg bites with vegan Just Egg (cubed cooked potato and thyme, or spinach and sautéed mushroom) and pack those.
Sushi is a hit and easy to pack - cucumber, tofu, mango, avocado, shredded carrot
