Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the zucchini and red bell pepper into bite-sized pieces and place them on the baking sheet.
Drizzle the vegetables with extra virgin olive oil and sprinkle with sea salt and black pepper, tossing to coat evenly.
Roast the vegetables for 18-20 minutes until they are tender and slightly caramelized at the edges.
While the vegetables roast, bring a large pot of salted water to a boil and cook the red lentil penne according to package directions until al dente.
In a large skillet over medium heat, add the minced garlic and dried oregano, sautéing for 1 minute until fragrant.
Stir in the marinara sauce and rinsed cannellini beans, simmering for 5 minutes to allow the flavors to meld.
Drain the pasta and add it to the skillet along with the roasted vegetables and nutritional yeast.
Toss everything together until the pasta is well-coated and the nutritional yeast has created a slightly creamy texture.
