Preheat oven to high broil. Roast sliced tomatoes and zucchini until golden brown. In the meantime, chop ginger, garlic, and scallions.
Cook the garlic and ginger in 1 Tbsp of olive oil for 1-2 minutes in a pot. Combine 2 cups water, cashew butter, maple syrup, and soy sauce. Stirring the sauce continuously, bring to a boil, then reduce heat to medium-low and cook until the sauce thickens, around 5-7 minutes.
Add the bag of kale to the sauce, and stir until the kale is wilted. Add the roasted tomatoes and zucchini, along with the crushed red pepper.
Add the noodles to the cashew butter and vegetable sauce. Toss to coat. Garnish with scallions and serve
