Preheat the oven to 200°F (90°C).
Make the fried plantains as directed below. When the fried plantains are cool enough to handle, slice them into bite-size pieces. Transfer the slices to a baking sheet and keep them warm in the oven.
Place the same pan in which you fried the plantains over medium heat, add the butter, and heat until sizzling. Crumble the tofu into the pan. Sprinkle in the eggy seasoning mix. Stir to evenly distribute the spices.
Cook the tofu over medium heat for 5 to 7 minutes, stirring occasionally, until slightly browned. As the tofu cooks, feel free to taste and adjust the seasoning. You might want to add a little more salt, pepper, nutritional yeast, or turmeric.
Once the tofu is as browned as you want it, assemble the sandwiches: Butter the toasted hard dough bread. Take 2 slices of toast and arrange 2 or 3 slices of the fried plantain on each piece of toast. Pile the scrambled eggs on top of the plantains. And if you like, drizzle the sandwiches with a little hot sauce. Then, top each sandwich with another piece of toast.
