If using wooden skewers, be sure to soak them for at least 20 minutes prior to grilling.
Preheat grill to medium-high heat.
Toss bell peppers and zucchini in olive oil. Season with salt and pepper.
Thread bell peppers, zucchini, and tofu onto skewers. I ended up having more veggies than tofu, so I had a few skewers that were just veggies. No big deal - just do whatever pattern or ratio of tofu to veggies that you'd like!
Place on grill and cook for ~15 minutes, turning every 5 minutes.
Once cooked, they should have visible grill marks but not burnt. If you find they are getting too charred, turn your heat down.
Remove from grill and serve with peanut dipping sauce.
Enjoy!!
