Drizzle 4 slices of bread from both sides with a little oil and sprinkle some garlic powder on top. Heat them up in a pan or on the grill for a few minutes.
Prepare a batch of my vegan cheese sauce or skip this step if you use store-bought cheese.
Top two slices of bread with a heaped tbsp of the vegan cheese sauce.
Then add the spinach, onion mixture.
Top with the carrot slices.
Add another layer of vegan cheese sauce.
Finally, top with the other slice of bread. Cook on medium heat in a skillet or on the grill for 2-3 minutes or until golden brown. Flip and cook for 2-3 minutes more, then remove from pan. Enjoy!
