The recipe is very simple: lightly spread four pieces of whole wheat bread with mayonnaise, sprinkle over some Cajun seasoning and then some cheddar cheese. Bake in a 375°F oven for 10 minutes.
I made my own Cajun seasoning with the following ingredients:
2 Tbsp paprika (I used a mix of 1 Tbsp normal paprika, 1/2 smoked and 1/2 sweet)
3 Tbsp herbes de Provence
1 Tbsp salt
1 Tbsp black pepper
2 tsp cayenne
2 tsp white pepper
