- Preheat the oven to 400ºF/200ºC. Toss the tomatoes and zucchini with one tablespoon of olive oil, season with salt and black pepper, and arrange in a single layer on a baking pan lined with parchment paper. Cook for 30 minutes, flipping halfway through. 
- Add the water, milk of choice, and salt to a medium pot. Bring to a boil over medium-high heat.  
- Once boiling, pour in the polenta with one hand while continuously whisking with the other hand. This helps prevent clumping. Reduce heat to low and simmer whisking often for about 5 minutes as the polenta starts to thicken. 
- Cover and cook for 25-30 minutes, stirring once every 5 minutes. 
- Taste the polenta to check for doneness. Once done, remove it from the heat, and stir in two tablespoons of butter. Put the lid back on for an additional 5 minutes (off the heat).  
- Serve it in a bowl with the roasted veggies on top, a drizzle of olive oil, fresh herbs, and a little salt. Plus any other additional toppings if desired.
