Spread mayonnaise on each slice of bread; brush the flip sides of bread slices with olive oil.
Assemble the sandwiches by layering chicken, cheese, salami, pepperoni, pastrami, lettuce, bacon and tomato on half the slices (mayonnaise side up); top with remaining bread slices (mayonnaise side down).
Place sandwiches on panini press preheated to 400°F; adjust cover to sandwich thickness; close press and grill ~6 minutes, until bread is toasted and cheese has melted.
