Preheat the oven to 350°
Put the ingredients in a blender and blend until it’s the consistency of cream. You shouldn’t be able to see pieces of the nuts.
Pour the cream into a medium sauce pan and heat on medium for 4 to 5 minutes, stirring constantly. The mixture should be thick and stretchy, like melted cheese. Remove from heat and cool for ten minutes.
Brush the olive oil on one side of each slice of bread and put the oiled side face down on a grill pan or a skillet. Spoon the cheese over one piece of bread, add two tomato slices and three basil leaves. Gring fresh cracked pepper on top if desired. Leave the slice that doesn’t have the cheese on it aside.
Put the pan in the oven and bake for approximately 4 minutes or until the basil leaves begin to crisp up. Use an oven mitt to grab the handle of the pan and move to the stove top. Turn the heat on to medium-high and toast the bread until it’s golden brown. Put the piece of bread that was set aside on top and flip to brown.
