Low Syn Scary Spider Sandwiches | Slimming World

These Low Syn Scary Spider Sandwiches are another fun, easy idea for Halloween. The kids will love them, and they’re so easy they can even help make them.


For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff in the blurb 👍

As you can see, this recipe uses Black Olives. We used Tesco Pitted Black Olives in Brine which are 2 syns for 25g. We used 2 Olives which weighed approximately 2g each, and we’re slicing them up and using 2 thin slices on each sandwich so it’s up to you if you want to syn the olive or not.

Personally we wouldn’t syn it as the amount we’re using is negligible (If we were eating more than a whole olive then we would syn it). As we’ve said, the choice is yours whether you syn it or not.


We’ve used egg as a filling for these Low Syn Scary Spider Sandwiches, but you can use whatever filling you want, just remember to add count the syns if it isn’t syn free. You could even have these on an SP day!

Synning the bread

For this recipe we used a Warburtons Wholemeal 400g loaf, and cut out the shapes using a Frylight lid. Two discs of bread weigh around 6-7g which works out at 0.6 syns per sandwich. That means you can have 2 sandwiches for just over 1.2 syns, but as you know we need to round it up, so that 1.5 syns for 2.

Another thing to mention is the Red Peppers from a jar. We like to use Lidl Freshona Roasted Red Peppers in Sweetened Vinegar, as they are syn free. Whichever brand you decide to use make sure they are in sweet vinegar or brine, not in oil. We don’t want to be adding any syns now do we?

  1. Boil the eggs for about 11 minutes, or until they are hard. Remove the eggs from the pan and plunge them into a bowl of icy water until they are cool
  2. Peel the eggs and place them in a food processor along with the Quark, white wine vinegar, mustard powder and a bit of salt and pepper. Blitz for a few seconds until the eggs are finely chopped and blended well
  3. Cut 12 slices from the olives. Then cut 12 small triangles (for the fangs) and 12 small cubes (for the eyes) from the pepper
  4. Lay 6 of the bread discs down, then spread some of the egg mix on each one
  5. Arrange the carrot strips on 3 of the discs to make legs, then do the same on the remaining discs with the chives
  6. Place 2 'fangs' at the front of each disc to resemble teeth (a cocktail stick is good for doing this)
  7. Top with the remaining discs of bread
  8. Take each slice of olive and spread a tiny bit if the egg mixture on one side, then press 2 of them onto the top of each sandwich above the fangs
  9. Using a cocktail stick pick up each small cube of pepper and place it in the centre of each olive slice
