Lightly drizzle the bread with extra virgin olive oil. Toast in a frying pan over medium heat until golden brown and crisp, 1–2 minutes per side.
While the bread is toasting, cut the avocado in half, remove the pit, and slice it thinly.
Spread the cottage cheese generously over each slice of toast.
Sprinkle with freshly ground black pepper.
Arrange the avocado slices over the cottage cheese.
Sprinkle with kosher salt to taste.
Drizzle the balsamic glaze in thin ribbons over the toast.
Sprinkle with sesame seeds or mixed seeds. Add chili flakes if desired.
Serve immediately while the toast is still crisp.
