Take 2 slices of your bread of choice and toast them to a light brown. then take a spoonful of olive tapanade and spread on one slice of bread. Next take a handful of arugula salad and lay it on the bread. Then lay out the feta slices, followed by the avocado slices. Slice your tomato(es) and before putting them on the sandwich, season each slice with a pinch of salt, a grind of pepper, and oregano herbs. Lay the tomato over the avocado and then drizzle with olive oil and the balsamic vinegar reduction (the reduction is important because regular balsamic is too fluid and will make the bread soggy). Then top off the sandwich with the other slice and voila, you have a flavor-rich and healthy garden salad sandwich.
