This tasty sandwich came about as my plant based version of an avocado and egg sandwich.

I find plain cooked tofu and egg whites resemble each other in texture and flavor. And if you enjoy egg whites, you should take to this tofu sandwich with no trouble at all!

The tofu is prepared as simple as possible since that’s what you generally do with egg whites. The only ingredients added are garlic powder, salt, and pepper during cooking to give a slight flavor.

And frankly, once the sandwich is complete, that’s all it needs. Cooking the tofu on a hot griddle or skillet will sear it, giving the tofu a light golden color.

To add even more flavor, I’ve added flavorful sauteed onions. I have a thing for them lately, and they never disappoint! If you’re not a fan of onions, feel free to leave them out.

A Protein Rich Sandwich

This sandwich is loaded with protein not only from the tofu but also from the bread I used.

  • Bread. At the moment I’m loving Dave’s Killer Bread. Two slices of this bread gives me 10 grams of protein and 10 grams of fiber. That’s pretty amazing in itself.
  • Tofu. The tofu will add another 15 grams boosting the protein content of this sandwich to 25 grams. That’s slightly more than half of the day’s recommended amount for the average adult female and slightly less for males.

All in all, it’s a well-balanced sandwich I could every day!

  • 1416 oz tofu (extra firm, firm or high protein)
  • 2 tablespoons olive or grapeseed oil, divided
  • garlic powder
  • mineral salt
  • fresh cracked pepper
  • 1 onion, thinly sliced
  • 1 tomato, thinly sliced, optional
  • 12 medium avocados
  • 6 slices bread of choice
  • leafy greens of choice
  • favorite mustard or vegan mayo, to spread


Slice and press tofu: Remove tofu from package, turn on it’s side and carefully slice into 3 slabs. Place slabs between 2 clean dishcloths or towels, lay a heavy object over top to press out excess moisture. I used my large cutting board but a heavy cookbook will do the job too. Let set under pressure for about 10 minutes.

Saute onions: Peel and cut the ends off the onion, lay onion cut side down and cut in half. Slice onion into thin strips, about 1/8 – 1/4 inch. Heat 1 tablespoon oil in a skillet or medium size pan over medium heat. Add onions and cook, stirring frequently, until golden and browned on the edges, about 10 minutes. Remove from pan and set aside. If you happen to leave your onions in the pan take note that they may continue cooking from the heat of the pan, pay close attention so they don’t burn too much.

Pan-fry tofu: Heat 1 tablespoon oil over medium-high heat in a cast iron skillet or pan. Add tofu and cook without touching for about 4 – 5 minutes per side, or until golden brown. Sprinkle with salt and garlic powder after the first flip.

Prepare bread & avocado: Toast your bread, or not, and slice your avocado. You may even prefer to mash your avocado right in its shell with the back of a fork and spread like butter. I find I use the latter method most often.

Assemble: Layer your sandwich as you like. I layered mine from bottom to top with mustard (dijon and habanero mix), leafy greens, tofu, sauteed onions, salt & pepper, avocado and more mustard. Every bite was so delicious!

Serves 3


I suggest using only non-gmo, pref. organic, tofu. Tofu is very inexpensive and non-gmo/organic tofu is only a few cents more. Make the splurge!

The addition of sliced tomato on the sandwich is delicious but here I chose to eat them separately.

  1. This was so good I couldn’t even believe it! Used my favorite vegan mayonaise: Follow Your Heart, my favorite mustard: Boar’s Head Delicatessan Style Mustard and instead of garlic powder, salt and pepper – I used a fantastic seasoning salt made by my dear friend of her Grandmother’s concoction. I love it. And I love this sandwich. You made my day!
