Vegan Grilled Cheese Sandwich

Slice the carrot lengthwise into thin strips and cook in an oiled skillet with salt and a few tablespoons of broth, covered, until tender, about 12-15 minutes, flipping halfway. 2. Meanwhile saute the diced onion in oil for 4-5 minutes, then add the spices, soy sauce, balsamic vinegar, and spinach; turn off the heat after a minute. 3. Drizzle the bread slices with oil, sprinkle with garlic powder, and toast briefly. 4. Layer two slices with vegan cheese sauce, the spinach-onion mixture, carrot slices, and more cheese sauce, then top with the remaining bread. 5. Cook in a skillet 2-3 minutes per side until golden brown.
