Mayonnaise Sandwich

This Mayonnaise Sandwich is a tasty and easy-to-prepare vegetarian sandwich made with veggie stuffing and my homemade vegan and Eggless Mayonnaise. This light and mildly flavored sandwich is perfect for a summer picnic or to serve as a finger snack during parties or get-together.

About This Recipe

These mayonnaise sandwiches are light and refreshing. The boiled potatoes blend perfectly with the mayo to produce a nice creamy spread. The added veggies give a crunch and nutritional boost to the sandwich and the seasonings are mild, but perfectly paired with the flavor of the mayo.

There are many ways a veg mayonnaise sandwich can be made. Here I give you the basic method for preparing the mayo filling and constructing the sandwich as well as tips on ingredients and seasonings. Once you have the basic idea, feel free to adapt the recipe to your preference.

It is also easy to prepare the mayo stuffing and have it ready to add to bread for a quick lunch or snack throughout the week.

This vegetarian recipe can easily be made vegan by using dairy-free mayo and vegan butter.

Ingredients you need

Besides a good quality Eggless Mayonnaise, the other key ingredient that makes this sandwich work are the soft-boiled potato cubes. The texture of the boiled potatoes works perfectly with the mayonnaise.

This recipe includes grated carrots

and chopped bell pepper (capsicum), however feel free to add different or additional veggies, including cabbage, steamed corn kernels and steamed green peas.

Just be sure that the proportion of veggies to mayo gives you a nice consistency so that it spreads well on the bread.

Any bread can be used, but for a healthy version include whole wheat bread or rye bread or multi grain bread.


How to make Mayonnaise Sandwich

  1. In a mixing bowl take ⅓ cup grated carrots and ¼ cup finely chopped bell pepper (capsicum). You can also add veggies like some steamed corn kernels, steamed green peas and shredded cabbage at this step.
  2.  Add one medium-sized potato, which has been boiled, peeled and chopped. The addition of potatoes are optional but I do recommend adding them as they make the sandwiches filling and hearty. They also give a good texture and taste.
  3. Add ⅓ cup Veg Mayonnaise. You can use your preferred brand of eggless or vegan mayonnaise. Instead of mayo you can use greek yogurt or thick sour cream.
  4. Add ¼ teaspoon freshly ground black pepper and ¼ teaspoon ground mustard (mustard powder).

If you do not have ground mustard, then simply crush ⅛ teaspoon mustard seeds in a mortar pestle. Or you can add ¼ teaspoon dijon mustard.

  • Mix very well. For a slightly sweet taste, you can also add ¼ to ½ teaspoon sugar. But do keep in mind that if your mayo has a more sweet taste then don’t add sugar. If you want, you can also add some red chili flakes or some dried herbs like oregano, thyme, basil.
  • Spread butter on the bread slices.
  • Now spread the stuffing on the bread slices.
  • Place on top the remaining buttered slices and slice the sandwich in rectangles or triangles or small squares. At this point, if you’d like, you can toast or grill these sandwiches.

9. While serving the veg mayonnaise sandwiches you can garnish them with some grated carrots and grated cheddar cheese. Accompany them with some banana chips, potato chips or potato wedges.

  • They make for a good after-school snack for kids as well as a hearty evening snack.

Serving Suggestions

These mayo sandwiches also make for a perfect light breakfast, lunch or snack. As they taste great cold, these sandwiches also work great to pack in a picnic or as a packed lunch. Easily multiply the recipe and serve them as a finger snack during parties. 

You can serve veg mayo sandwiches plain or accompany them with some potato chips or french fries or potato wedges.


For a vegan version, simply use a vegan mayonnaise and plant-based butter or just skip spreading the butter on the bread. Or else, if you are just looking to avoid eggs, use an eggless mayonnaise, or else make your own homemade eggless mayonnaise.

This version is for a cold, non-toasted sandwich, but you can easily toast or grill these mayonnaise sandwiches if you prefer a warm sandwich with a crispy crust.
