Mayonnaise

Easy homemade mayo. Cheaper than storebought 'natural' mayo by a long shot. The optional whey left over from yogurt making preserves the mayo. Mayo made with whey will keep for 2-3 months in the fridge.

Whatever Quiche

Low carb. Use whatever non-starchy vegetables you like, like dark leafy greens, artichokes, sundried tomatoes, peppers, onions, sliced mushrooms, pitted olives. Don't be afraid to add fat.
