Preheat a cast iron pan with olive oil, then sauté the shallots and garlic for 1-2 minutes or until fragrant.
Add in the squash, and toss to combine and ensure all of the squash is coated with oil. Season with a pinch of salt, then continue to sauté until the squash browns, softens, and becomes slightly translucent, approximately 10-15 minutes.
Notes
Be sure to watch the squash as it cooks so that it does not overcook and become mushy, or too browned.Keep the heat at a steady medium to allow the squash to render down evenly.Cut the zucchini as evenly as you can. Uneven slices will result in uneven cooking.
