The meatball that stays tender

Makes one full skillet in about 40 minutes, most of it in the oven: dinner tonight and lunch tomorrow, or one big dinner if that is where your appetite lands today. The whole skillet holds roughly 100g of protein.

Heat the oven to 425°F with a 12-inch cast iron skillet inside. Toss the carrots with two tablespoons of olive oil and a big pinch of salt, carefully tip them into the hot skillet, and roast 15 minutes.

While they roast, stir the breadcrumbs into half a cup of the yogurt in a mixing bowl and let it sit five minutes, until it turns to a thick paste. Add the lamb, the egg, one grated garlic clove, the cumin, a teaspoon of salt and plenty of pepper. Mix with your fingertips just until you can no longer see streaks, then roll into 12 to 14 balls about the size of a golf ball.

Push the carrots to the edges, nestle the meatballs in the middle, and roast 14 to 16 minutes, until the tops are browned and the center of a meatball reads 160°F on a thermometer. Stir the rest of the yogurt with the juice of half the lemon, the second garlic clove minced fine, and a pinch of salt. Spoon it over everything.

Why this works: breadcrumbs soaked in yogurt make a paste that holds moisture inside the meatball while it cooks. Mixing only until combined matters just as much, because lamb that gets worked hard packs into a dense, bouncy ball.

Everything keeps 3 days in the fridge. The meatballs are good cold, split open over a salad or tucked into a pita, and the carrots are as good at room temperature as they are hot.

No recipe, just an order of operations, for a morning that wants something savory with a crunch. Slice half a crisp apple into thin wedges. Cut two ounces of provolone into thick slabs rather than thin slices. Fold three or four slices of hard salami into quarters and lay everything on a plate with black pepper over the cheese. Take a piece of each in the same bite.

Buy the provolone as a block or at the deli counter, and get the aged kind if they have it. It tastes sharper than the mild sliced stack, and against the apple it carries more flavor than you would think. Roughly 20g of protein, depending on the brands.

A handful of almonds and two clementines from the produce aisle. The almonds bring the protein, and the fruit makes it feel like a snack instead of a mouthful of nuts.

Stir a spoonful of dry milk powder into mashed potatoes, oatmeal or the base of a soup. It dissolves and tastes like creaminess, and it adds protein to food you were already making. Check the label for the protein per serving, because brands differ.

In the canned fish aisle, next to the sardines, look for mackerel. It is firmer and milder than sardines. Mash a can with lemon juice and a spoonful of mustard, then eat it on toast or crackers or fold it into hot rice.

Ground meat has its own rule. On a steak, bacteria stay on the outside, and a hot sear handles them. Grinding mixes that outside into the middle of every meatball, so the whole thing has to get hot. USDA says ground lamb should reach 160°F, measured with a food thermometer. Slide the probe in from the side so the tip sits in the center of the meatball, and check one from the middle of the pan. A thermometer costs a few dollars at most grocery stores, and it lets you pull the meatballs the minute they are done, which is also how they stay juicy.

For the day this week when the stove is not going to happen: a mug of instant oatmeal made with hot milk instead of water, a spoonful of peanut butter stirred in until it melts, and a pinch of salt. Soft, warm and easy, with real protein in the mug.
