Arrange tomato slices on a platter and season with ½ teaspoon salt.
Meanwhile, combine the poppy seeds, sesame seeds, dried garlic and dried onion in a small skillet. Cook over medium, shaking the pan occasionally, until the mixture is fragrant and golden brown, about 2 minutes. Transfer to a small bowl, stir in ½ teaspoon salt and ¼ teaspoon pepper and set aside.
Scatter the red onion on top of the tomato slices and drizzle with the olive oil and Worcestershire sauce, if using.
Using a spoon, dollop the cottage cheese on top.
Garnish with the herbs and the toasted spice blend; serve with bread.
