My dad eats these right out of the jar. Just 4 ingredients for a stunning and tangy snack.

If you prefer a slightly milder tang, swap half of the white vinegar for water while keeping the beets and salt the same. For a hint of sweetness that’s still low carb, stir in a small amount of your favorite granular sugar substitute (like erythritol or monk fruit) to the warm brine until it dissolves. If you like a bit of spice, add a pinch of red pepper flakes or a few black peppercorns to the jar before pouring in the brine. You can also use apple cider vinegar instead of white vinegar for a softer, fruitier tang. For meal prep, boil a dozen eggs at once and make a double batch of brine in a larger jar—these keep well in the fridge, so you’ll have a week’s worth of grab-and-go, high-protein snacks ready whenever you or your “eat from the jar” family member wants one.
