Mixed Veggie Tuna Salad Sandwich Recipe (Ready in 15 Minutes)

One of the reasons I love this mixed-veggie tuna salad sandwich is that it’s quick, crunchy, and very lunchbox-friendly.

And the filling has tuna, onion, peas, corn, and red pepper, so every bite has a little color and a little snap.

The mayo keeps it together without turning the sandwich too soft or messy.

I also love that it uses plain pantry and freezer stuff, which means you can usually pull it off without a special trip.

The toasted bread gives the filling something sturdy to sit on, and that matters more than people admit.

If your lunch needs help and is fast, this one shows up on time.

Ingredients You Need

• 1 tbsp chopped red pepper
• 1 tbsp peas
• 1 tbsp corn
• 1 tbsp finely chopped onion
• 3 oz canned tuna
• 1 tsp low fat mayonnaise
• 1/8 tbsp salt
• 1/8 tbsp black pepper
• 2 whole wheat toast slices

How to Make Mixed Veggie Tuna Salad Sandwich

1. Add the chopped red pepper, peas, corn, and finely chopped onion to a mixing bowl.

2. Add the tuna over the vegetables.

3. Add the low fat mayonnaise.

4. Season with the salt and black pepper.

5. Stir the tuna mixture until the vegetables are tucked through and the mayo coats everything.

6. Keep mixing until the tuna breaks into smaller pieces and the filling looks even from edge to edge.

7. Toast the two whole wheat bread slices in a dry pan until they look browned.

8. Spoon the tuna filling onto one toast slice.

9. Spread it out enough to cover the bread from one end to the other.

10. Place the second toast slice on top.

11. Cut the sandwich and serve while the toast still has a little crunch.

Why This Sandwich Hits

The vegetables keep the filling from tasting flat, and they give the sandwich more texture than plain tuna and mayo ever could.

Toasting the bread makes a big difference here because the filling stays inside better and the sandwich feels way less floppy.

Little Sandwich Notes

Chop the onion small so it mixes through the tuna instead of sitting in one sharp bite.

Spread the filling all the way to the edges so each half looks full after you cut it.

Toast the bread in the pan just until browned because very dark toast can overpower the filling fast.

What To Serve On The Side

This goes well with cucumber slices, fruit, or a small salad if you want something cool beside it.

Chips work too, and I wont argue with that.

If You Want To Prep Ahead

You can mix the filling and keep it covered in the fridge for up to 1 day.

Toast and assemble the sandwich right before eating so the bread stays crisp.

Quick Questions

Is the filling very mayo heavy?

No, the mayo is light here and mostly just helps the tuna hold together.

Do the peas and corn make it sweet?

They add a little sweetness, but the onion and pepper keep the sandwich balanced.

Use The Extra Veg

If you have peas, corn, or red pepper left, stir them into another tuna bowl or a quick rice salad later on.
