Let’s start by preparing our veggies for cooking. Wash, peel the squash, and dice into cubes. Do the same with the rest veggies.
Prepare the seasoning mix by whisking together tomato paste, salt, pepper, olive oil, nutmeg.
Transfer the veggies to your oven-safe cooking bag and top with the seasonings mixture. Massage the veggies until fully covered in the sauce.
Poke the bag with a toothpick in several places.
Next, transfer the veggie bag on a baking tray to the oven and bake for 50 minutes.
When ready, open the bag and place the veggies into a medium to a large pot. At this point, you’ll have some water in your bag. Some people like it, some don’t. I usually like to leave a little water in.
Add the second minced garlic clove on top and puree the vegetables with an immersion blender.
Taste again for salt and pepper.
Transfer the pot to the heated stovetop and take it to a boil, constantly stirring. Be careful, the mixture will start splashing so make sure not to leave it without attention.
Remove from heat, let it cool (It is usually served chilled).
Garnish with parsley and serve!
