We both loved this and felt that the Spice Cajun Remoulade Sauce was as essential as the fresh tomato and roast beef. The only change I made was to use white bread because I did not have any brown bread, also think this would be good on a light rye. This will be a regular in our house, thanks for the post.
The butter and remoulade are essential to this, adding fat and flavour. I used a very lean, rare roast beef. A healthy sprinkling of freshly-cracked pepper is a good thing!
