Dice the eggplant into 1/2-inch cubes. Place in a colander, sprinkle generously with salt, and let sit for 30 minutes until beads of water form. Rinse thoroughly and shake off excess water.
Heat 3 tbsp olive oil in a large skillet. Add rinsed eggplant and cook over medium-high heat, tossing every few minutes, until caramelized and golden brown on all sides.
Meanwhile, boil a large pot of salted water and cook penne pasta according to package directions. Drain and set aside.
Prepare pesto by adding basil, lemon juice, pine nuts, nutritional yeast, cayenne, salt, and pepper to a food processor. Blend until mostly smooth, streaming in olive oil as needed to reach desired consistency.
Toss cooked pasta with pesto until evenly coated. Add caramelized eggplant and cherry tomatoes, then gently toss to combine. Serve warm.

Notes
Japanese eggplants are ideal for this recipe as they caramelize beautifully without becoming spongy. Adjust pesto seasoning to taste—extra lemon for brightness, more cayenne for heat. Leftovers keep well refrigerated for up to 3 days.
