Here are some high-energy, easy-to-eat-en-route, sustaining snacks to make and share along the march route. So fill a thermos with hot soup, a baggie with spiced nuts or good granola, or a small sac of cookies packed with nutritious, delicious ingredients.
For a more substantial meal to eat with one hand while holding a sign in the other, there are cheese-filled bourekas and feta-and-spinach arayas.
And please don’t forget to drink plenty of water.
