Step 1: Press the Tofu : Drain tofu and wrap it in a clean towel or paper towels. Place a heavy object (like a skillet) on top and let it press for 15–20 minutes to remove excess water. Slice into even rectangular slabs (about 8–10 pieces).

Step 2: Caramelize the Onions : Heat olive oil (or butter) in a large skillet over medium-low heat. Add sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 20–25 minutes until golden and soft. Add brown sugar and balsamic vinegar in the last few minutes for extra depth. Remove from heat and set aside.

Step 3: Cook the Tofu : In another large skillet, heat 1 tablespoon olive oil over medium-high heat. Add tofu slices and season lightly with salt and pepper. Sear for 3–4 minutes per side until golden brown and crisp. Reduce heat to medium and brush BBQ sauce generously on both sides of the tofu. Cook for an additional 2–3 minutes, allowing the sauce to thicken and caramelize slightly.

Step 4: Assemble the Sandwiches : Toast the buns lightly for added texture. Spread a thin layer of BBQ sauce on the bottom bun. Add a layer of greens or coleslaw. Place 2–3 slices of BBQ tofu on top. Spoon caramelized onions generously over the tofu. Add the top bun and serve immediately.
