25 Weird and Crazy yet Nutritious Sandwich Fillings

Here are 25 weird sandwich fillers for you to try. They're all safe and mostly nutritious, and they originate from all over the world—so take your time, relax, study the pros and cons, and get sandwich-making!

For all you starving carnivores, there are plenty of meat sandwich fillers; and for the vegetarians and vegans amongst you, there are alternatives.

I guess we all have our own ideas about what should go between two slices of bread, be it white, brown, rye, roggebrod, pumpernickel, farmhouse, or baguette!

For instance, I love banana and grated chocolate between wholewheat sliced as an energy food, but this pales into insignificance when compared to some of the following sandwich fillers.

These sandwich fillers are taken from various sources—myself, family, friends, students, low renters, those with strong stomachs, and other ardent sandwich makers. So make the most of each one and think of them as gastronomic experiments, with you as scientific guinea pigs.

If the Earl of Sandwich is looking down on us from his parlour in the sky, I can only say thanks for the invention, each day millions swallow your surname!

Bon appetit! And maybe someday you'll be inventing sandwich fillers of your own?

The first offering comes on wholemeal bread and is a nutritious mix of protein spiced up with a crunchy accompaniment, adding an edge to an interesting unseasoned lunchtime snack.

Ingredients: Fishpaste, gherkin, sausage, pickle, and fried egg.

Next up on the plate is a student's delight. When you've run out of staple foods and your cupboard is bare, your fridge empty and the freezer a vast white space of nothingness, reach for the last two items available.

Ingredients: French mustard and Apricot preserve.

A thin layer of French mustard on one slice. A thin layer of apricot preserve on the other. Enjoy?

This third sandwich would grace any vegetarian's lunch box. It has a common base but takes off with the addition of an unusual and peppery plant. So, prepare to have your tongue stuck to the roof of your mouth and your teeth full of little green mashed-up bits.

Ingredients: Crunchy peanut butter, alfalfa sprouts, mayonnaise.

Fourth is a low-rent affair that smacks of male desperation and quick-fix tactics. The saving grace is a little red vegetable. At a push, it could be toasted. Check this one out.

At number five comes this delicate yet eye-watering masterpiece. Four fascinating ingredients that would put a smile on any vegetarian's face and a stare of bewilderment on everyone else's.
