250 g9 ozlean boneless pork loin (2 thick chops)
250 g9 ozpeeled sweet potato, diced (1 medium)

Weights are for each food as described on its page: raw, cooked, or drained, as noted. Grams are the reference used for the math; ounces and cups are rounded US equivalents.

Directions

Preheat the oven to 400 °F (200 °C).
Toss the sweet potato with half the oil, the paprika, and salt, spread it on a baking sheet, and roast for 15 minutes.
Rub the pork with the minced garlic, oregano, salt, pepper, and the rest of the oil.
Add the pork and green beans to the sheet and roast 15 to 18 minutes more, until the pork reaches 145 °F (63 °C) in the center and is still juicy.
Let the meat rest for 5 minutes before slicing it thin.
Serve the pork with the sweet potato and green beans.

Why it is filling

Pork loin with the visible fat trimmed is a lean meat with plenty of protein, and sliced thin it is easy to chew. Roasted sweet potato provides carbohydrates and fiber with a sweet flavor that often appeals when eating is hard, and green beans add volume and more fiber with less risk of gas than beans or lentils. Everything cooks on one sheet with little oil.

In numbers, each serving has 30.3 g of protein and 5.8 g of fiber, with an energy density of 96 kcal per 100 g of the dish. In the satiety index by Holt and colleagues (1995), the foods that were most filling per calorie were those with more protein, fiber, and water and less fat.

High in protein: At least 15 g of protein per serving and 6 g per 100 kcal.
High in fiber: At least 5 g of fiber per serving, a fifth of EFSA’s 25 g daily reference.
Easy to digest: A soft dish with little fat (20 g or less per serving) and no large amounts of ingredients that often cause gas or nausea. This is an editorial call, not a measurement.
Low energy density: 100 kcal or less per 100 g of the dish: plenty of volume for few calories.

If your appetite is small

If half a serving is enough, save the rest: sliced pork keeps for 3 days in the fridge and reheats well covered.
Eat a few slices of pork first and then the sweet potato, so the protein doesn’t get left on the plate.
