An Easy Sauteed Spinach with Creamy Yogurt Sauce (plus Leftover Yogurt Sauce Mashed Potatoes!)

Your drive-by recipe of the week: I sauteed an entire bag of spinach with a few cloves of garlic (instead of putting raw garlic in the sauce; raw garlic induces an upset stomach in some people), then made the rest of the creamy yogurt dressing from this recipe as written. I've been very into putting plain yogurt into everything lately! I've also been very into putting a fried egg on everything lately, which may have been partially spurred on by the fact that we participated in a meat CSA (Community Supported Agriculture) program this winter and were thus given 3 dozen eggs a month...

There was a lot of yogurt sauce left over from this recipe, which got recycled into these a few days later:

The yogurt sauce just gets used in place of milk or whatever other liquid you would mix into your mashed potatoes at the end. I think I still used a little bit of butter to soften things up as well.
