Season with salt, pepper and oregano and a drizzle of olive oil.
Spoon the seasoned tomato mixture over the rusks and let them sit for a few minutes.
Chop olives and top them over the tomatoes.
Finish up with some crumbled feta cheese and roughly chopped basil.
Notes
If you can, use sea salt flakes to season this Greek salad. It doesn't fully melt, and gives you those small bursts of flavor to enjoy in every bite.
Remember to allow the rusk to soften for a few minutes before you serve. Barley rusks can be break-your-teeth hard.
If you can't find any rusk, you can slice some baguette (or any other bread for that matter) and bake it in an oven for a couple of hours until dry and crispy, and use it instead.
You can also chop up the rusk (or crusty bread that you're using), and roughly chop the tomatoes instead of grating them. Then, assemble everything in a bowl and toss well- a deconstructed version of the classic salad.
