Cut the pressed tofu into 1-inch cubes and place them in a mixing bowl.
In a small bowl, whisk together soy sauce, maple syrup, minced garlic, and grated ginger to create the marinade.
Pour the marinade over the tofu cubes, ensuring each piece is well coated, then cover and refrigerate for at least 30 minutes to absorb the flavors.
While the tofu marinates, prepare your vegetables by cutting bell peppers and onions into chunks, then set aside.
Preheat your grill to medium-high heat, and soak wooden skewers in water to prevent burning.
Thread the marinated tofu cubes onto the skewers, alternating with bell pepper and onion chunks for color and texture.
Brush the assembled skewers lightly with olive oil to promote crisping and prevent sticking.
Place the skewers on the hot grill, listening for the sizzling sound as the edges start to char and develop a smoky aroma.
Cook the skewers for about 8-10 minutes, turning occasionally, until the tofu is crispy and golden brown with slight charring.
Remove the skewers from the grill and let them rest for a couple of minutes; the crispiness will set and flavors deepen.
Serve the skewers hot, enjoying the crunchy exterior, smoky aroma, and tender inside with your favorite dipping sauce or rice.
