Soak 1 cup of cashews in water for at least 2 hours.
Preheat your oven to 400°F (200°C). Spread chopped cherry tomatoes and whole garlic cloves on a baking sheet, drizzling with olive oil, and roast for about 25 minutes.
In a blender, combine soaked cashews, roasted tomatoes, garlic, and a handful of spinach. Blend until smooth and creamy.
