Preheat oven to 400 degrees. Cut heirlooms in half, and chop the beefsteaks. Place them on a baking sheet lined with parchment paper and drizzle with a good quality extra virgin olive oil and add a pinch of salt. Roast for 30 minutes.
Add to blender once cooled. Have a medium-sized pot set up on the stovetop to transfer the soup once pureed. Puree until creamy and smooth and no lumps remain.
Transfer to pot, add 1 cup of warmed milk along with 1/2 can of tomato sauce. Once this is well combined, puree a second time in two batches.
Season with salt and pepper to taste, and simmer for 15 minutes on low heat.
Garnish with finely grated Pecorino Romano cheese and a sprinkle of parsley flakes or fresh basil ribbons. Or add a little watercress, and some of the roasted heirlooms.
Serve alongside a grilled cheese or my Pepperoni Pinwheels which you can find on my blog.
