This delectable sandwich with roasted tomatoes is brimming with nutritious vegetables and an amazing taste! The tomatoes are roasted to excellence and joined by creamy avocado, crispy red onions, and basil within a toasted buttery bun. These effortless vegan sandwiches are loved by everyone!
Spread olive oil on a medium-sized baking sheet. Slice the tomatoes and place them in groups of 3-5 on the pan. Drizzle more olive oil over them and then season them with salt and pepper. Roast them in the oven for 15-20 minutes.
Meanwhile, heat a frying pan to medium heat. Place 1 tablespoon of butter in the pan. Add the tops and bottoms of the buns, face-down once the butter has melted. Let them toast for 1-2 minutes and then promptly remove them before they burn. Repeat these steps until the insides of all the buns are toasted.
Slice the avocados and red onions. Remove the basil leaves from the stems.
Assemble the sandwiches by adding the roasted tomatoes, red onion, avocado, and 3-4 basil leaves to the bread.
