Preheat your skillet on medium heat.
While the skillet is preheating, mince your garlic. Add butter to the hot skillet and melt completely.
Now add in garlic. Cook for 5 minutes, stirring a couple times to prevent the garlic from burning.
Add in tomatoes and cover with a lid for 3-4 minutes. Remove lid and stir tomatoes around then recover for another 2-3 minutes.
While the tomatoes are cooking, chop the basil and spiralize your zucchini.
Stir in your basil and spinach, stir in and cook until wilted, about 2-3 minutes.
Add in zucchini noodles, stir in with the other ingredients, and cook for 1-2 minutes.
Serve immediately. Salt to taste.
