Utensils: Panini skillet/grill
Assemble the sandwich with protein, tomatoes, basil, mozzarella and balsamic glaze.
Place the skillet on medium high heat and spray it with olive oil.
Spread half of the mayo on one side of the sandwich.
When the skillet is hot, place the sandwich on the grill with the mayo side down (so it’s cooking). Allow it to cook for about 2 or 3 minutes, or until it is golden brown. Press down on the sandwich using the panini grill lid.
Spread mayo on the other side of the sandwich, and when ready, flip the sandwich over so the other side cooks (roughly same amount of time, maybe a little less time).
Remove the sandwich from the grill and enjoy!
