Using an olive oil mister, lightly spray a non-stick skillet to coat the bottom. Heat on medium-high heat (See Notes). Add bacon slices and cook 2 minutes per side. When done, place slices on paper towel to blot excess oil. Allow to cool while tofu cooks.
Add another light coating of olive oil to the pan. Lightly sprinkle both sides of the tofu slices with the McCormick seasoning and place in the heated pan. Allow to cook 2-3 minutes per side on medium heat until both sides are lightly browned. Remove from pan.
Lightly spray the panini pan with olive oil and heat over a medium-low flame. Assemble the sandwich on the bread in the following order: bacon slices, avocado slices, tofu slices. Place in panini pan and cover with press (See Notes). Cook for 2-3 minutes on the first side- bread should be golden browned. Flip and cook with the press on top for another 2 minutes. Carefully remove with silicon spatula.
Serve with mixed greens on the side.
