Spread butter over both sides of the slices of bread
Spread the half cheese on each piece of bread.
Add roughly 1 cup of pesto chicken on one slice
Add a couple of thin sliced of tomatoes on the other side
Combine slices and push down to secure grilled chicken tightly inside
Heat a non-stick pan or panini grill/griddle pan. Turn the heat to medium to low and fry the sandwich until both sides are golden brown and the cheese is melted.
Notes
Tips:1. Close the lid if using a pan to melt the cheese more quickly. 2. Watch closely to make sure it doesn’t burn (the heat on each stove/electric griddle may be different).3. You can make this pesto chicken panini on a grill or sandwich griddle as well.
