Simple Summer Sandwich

First drizzle the bread with a little olive oil and toast in a 400-degree oven until the bread is crunchy. While the bread is toasting, start slicing the tomatoes. Now would be a good time to sharpen your knife; I personally like paper-thin tomato slices and to achieve that goal, you need a really sharp knife. Put the tomatoes in a bowl and season with sea salt and olive oil. Slice the avocado and onions into very thin slices. Then just assemble each toast. I started with the tomatoes, then avocado, then onions, drizzled with olive oil and sprinkled with sea salt and garlic powder.
