Soften the butter to room temperature and add it to a bowl or a stand mixer bowl. Beat on high with a mixer for 3 to 5 minutes until the butter is light and fluffy. Slowly add in your mayonnaise and continue to beat on high, incorporating it into the butter.

Add your garlic salt, dill, onion powder, salt, and black pepper and continue to whip up the butter. Taste and adjust the seasonings to your liking. Set aside.

Brush your bread slices with the olive oil and toast the slices in a skillet until they are toasty brown. Set them aside to cool.

When the bread is cooled off, spread each slice generously with the butter mixture you made. Make sure to add a decent amount and get the butter to the edges of the bread.

In a bowl, I add the cucumber and the radishes and add a sprinkle of celery salt and black pepper. Toss them to coat. Do the same thing with the onion slices in a separate bowl.

Layer the roast beef on half the bread slices and the turkey on the other slices.

Top the beef and the turkey with the radishes, cucumbers, and the onions. Add the red pepper spread or hummus or any other spread you like in small amounts on top of the deli meat. I place little dots of this in different places.

Add tomatoes to the turkey sandwiches. Add a little salt and pepper to the tomato slices.

Add some fresh parsley to the tops of the sandwiches.

Sprinkle chives across all the sandwiches. Then add a few pickles to the top of each sandwich. Display whole or you can cut in half. I usually serve these on a wood cutting board with some parsley or lettuce around them for aesthetics.
