Combine the cream cheese, mustard, mayonnaise and pimentos in a bowl and mix together. Stir in the Cheddar and black pepper. Taste to see if you need salt. Will keep for a week, refrigerated.
Spread the sliced bread with the pimiento cheese. Make faces using olives for eyes, cucumbers for ears, bell pepper for smiles and carrots and sprouts for hair. Use your imagination to make animals or funny faces.
Try making pimento cheese grilled cheese sandwiches, or topping burgers with pimiento cheese.
