Assorted open faced sandwiches on rustic parchment paper

Four mouthwatering open-faced sandwiches chill on parchment paper. The top-left one's got a sunny-side-up egg with avocado and tomato on rye. The top-right's a crispy combo of cheese, greens, and red onion on dark rye. The bottom-left rocks salmon, cucumber, and sprouts on whole-grain, while the bottom-right flaunts roasted veggies on whole-grain.
