Heat oil in a large skillet over medium heat. When shimmering, add onion and cook until just translucent. About 5 minutes. Add the celery, carrots, mushrooms and garlic and cook for another 3-4 minutes, until just softened.
Stir in the tomato paste and Italian seasoning. Toast for 2 minutes before adding in the red wine. Cook over high heat until the alcohol has cooked off, about 2-3 minutes.
In a small bowl, whisk together coconut cream (melt in microwave if solid), miso paste and soy sauce. Add to the pot along with the chopped tomatoes and lentils. Bring to a boil then reduce the heat and simmer for 15 minutes.
If the sauce seems too thick, add up to 1/2 cup vegetable broth. If you prefer a thicker sauce, simmer uncovered until the liquid has reduced. Once the desired consistency is reached, remove from heat and stir in the balsamic vinegar.
Serve warm on top of polenta with fresh basil and a drizzle of olive oil if desired.
For the Sweet Corn Polenta
Bring 2 cups of water to a boil in a small saucepan. Add the dry grits, corn kernels and salt and cook covered, stirring frequently for 15-20 minutes, until all the water is absorbed.
Stir in the honey and olive oil. Serve warm.
