Preheat oven to 350 degrees Fahrenheit
Prepare shallow baking pan to prevent sticking
Cut tofu into 1 inch cubes and combined with pesto in a bowl until coated
Arrange coated tofu in baking dish and bake 15 minute (i baked it longer to make it extra crispy
Cook pasta until al dente; drain and return to pan
Add marinara sauce to pasta and stir to coat; heat over medium heat until hot
I stirred the tofu into the sauce and pasta but you can serve with tofu on top
Top with pine nuts if you use them and some vegan parmesan cheese. Both are optional
