Place the eggs in a saucepan and cover them with cold water by about one inch. Bring the water to a boil, then turn off the heat and cover the pot. Let the eggs sit for ten to twelve minutes for firm, creamy yolks.
Move the eggs into a bowl of ice water right away. Let them cool for five minutes so the shells loosen easily. Tap each egg gently, peel it, and cut it in half.
Rinse the cucumber, tomatoes, and mini peppers, then pat them dry. Slice the cucumber into thick rounds and halve the tomatoes. Cut each pepper in half lengthwise and scoop out any seeds.
Add the cream cheese or Greek yogurt to a small bowl. Stir in the shallot and herb seasoning until smooth and evenly speckled. Taste it and add a pinch more seasoning if you want a bolder flavor.
Spoon or spread the seasoned filling into each pepper half. Keep the layer generous but neat so it doesn't spill over. Finish with a light sprinkle of seasoning on top for color and flavor.
Spoon the cottage cheese into a small bowl or ramekin and place it near the center of the platter. Add a light pinch of seasoning over the top. This makes the cottage cheese the star that everything else surrounds.
Fold or roll the turkey slices and tuck them around the bowl. Add the halved eggs, crackers, olives, tomatoes, and cucumber in small groups. Leave a little space between sections so each food looks distinct.
Slice the avocado last so it stays fresh and green. Fan the slices onto the plate and sprinkle with seasoning. Serve right away, or chill the plate for fifteen minutes if you like it cold.
