Drain and dry the tofu. Then, cut it into thin slices.
Place tofu slices inside a medium-sized bowl and add 2 tbsp of olive oil, coconut amino or soy sauce, vinegar, and seasonings. Seal it, shake it and place it in the refrigerator while you prepare the rest of the ingredients.
Prepare the mayo ketchup. Add mayo, ketchup, Dijon mustard, and garlic powder to a mixing bowl. Whisk until well combined. Cover and place inside the refrigerator until you are ready to assemble the tripletas.
Preheat a large saucepan to medium heat and add 1 tbsp olive oil.
Add sofrito and saute until fragrant, for about two to three minutes. Add beefless steak tips, sliced portobello mushrooms, and sliced tofu. Add more seasonings to taste. Cook for about 5 minutes.
Meanwhile, cut the bread loaf in half to open them up like a book. Take meat replacements out of the saucepan. Lower heat to low heat. Place the bread in the uncleaned saucepan. Heat bread on both sides for 1-2 minutes or until lightly toasted.
To assemble the tripleta, spread some mayo ketchup over half of the bread. Add meat alternatives, cheese, lettuce, and tomato. Add more mayo ketchup, and potato stick.
Close your tripleta sandwich and toast again if you like. Enjoy with a salad or potato chips.
