Wrap tofu in kitchen towel; cover with plastic wrap.
Place heavy weight on top; let stand 30 minutes to press out excess moisture.

cooking spray; bake about 2 minutes or until brown.
Turn tofu over; bake 5 minutes longer.
Meanwhile, spray nonstick wok or 12-inch skillet with nonstick cooking
spray; heat over medium-high heat until cooking spray starts to bubble.
Add oil; rotate wok to coat sides. Add bok choy and shallots; stir-fry 1
