Grill the bacon until crisp, then drain on kitchen paper. Use the olive oil spread on one slice of gluten free bread, then cover with the turkey, a little mayonnaise, and the lettuce.
Spread both sides of the next slice of bread, then put on top of the turkey. Spread a little mustard over the bread, then arrange the bacon on top, with the sliced tomato. Spread the last slice of bread and put on top. Press the sandwich down lightly, then cut in half diagonally..
