Pasta advices are good. A quick sauce for it is "Olio aglio e peperoncino" (oil, garlic and chili pepper), the variant I prefer with also some fresh tomato: stir fry garlic and chili pepper in extra virgin olive oil, add a few chopped fresh tomatoes (better the little, tasty ones) and stir fry them not too much, the sauce is fast enough to be prepared while pasta is cooking.
Another fast and healthy pasta recipe, is "pasta e broccoli " or "pasta e cavolfiore" (pasta with broccoli or cauliflower), you just boil (*) broccoli or cauliflower together with pasta, when pasta is ready, drain and season with extra virgin olive oil and ground pepper or chili pepper cand grated Pecorino cheese. It's particularly good for diet, because you can reduce the amount of pasta and increase vegetables and it makes you get up from the table replete, but having ingested fewer calories and carbohydrates and more fibre. Just 40g of hard semi-fat cheese grated (or flaked like in carpaccio, if you prefer) can season more than adequately one serving, it's compatible with most diets, its proteins complete the pasta ones and it gives a good amount of calcium, that's also better adsorbed than taking it from milk.
(*) this healthier variation is almost as tasty as sautéing broccoli, and it contains no cooked fats.
Fast hyperproteic, low calories recipe: "carpaccio". Put very thinly sliced raw meat on a dish, season with lemon juice, extra virgin olive oil, salt (and pepper or chili pepper or Tabasco sauce, if you like them) and flaked Parmigiano Reggiano cheese. Wait a few minutes if you prefer that lemon juice "cooks" the meat or eat immediately if you like raw meat.
Low calories, high fibre, high proteins: salad with mozzarella cheese, boiled eggs and tuna and/or anchovies.
Finally, a fast food healthier than hamburger: cured ham sandwich, it contains no cooked animal fats and the pig's fat, if raw like in cured and not cooked sausages, and if you take a moderate amount of it, is not unhealthy, it contains less saturated fats than beef or sheep fats, you just have to watch your total sodium intake, but if you like it, you can prepare it with unsalted Tuscan bread (the one that BTW should be used to prepare authentic "bruschetta"), this nicely solves the sodium issue too.
Also healthy the original sandwich recipe, with thinly sliced roast-beef in it, as it contains a very small amount of cooked fat, a lot less than hamburgers.
