For Mexican food, just give me a plate of beans and rice, plus some salsa and tortillas. Simple, cheap, filling, and I love it. Swap out the rice for fried eggs, and it's good too. If you feel like it, throw some extra goodies in with the rice or eggs: diced potatoes, bits of leftover hot dog, onion, diced tomato, a crumbled-up hamburger patty, whatever you need to get rid of.
When it comes to Italian food, I'm a sucker for gnocchi. For a quick lunch at home, though, we often opt for frozen tortellini and some pesto.
For Middle Eastern food, I like things wrapped in little packets, such as cabbage rolls. That kind of thing can also be found in many Eastern European cuisines and East Asian cuisines as well, and I generally like them all.
No French food beats a good old pain au chocolat—a croissant with chocolate inside.
But, to answer this question in a different way... When I read "international cuisines", I first through of foods that blend two different countries' cuisines together.
For Tex-Mex, I like burritos, and I also like burrito bowls.
For Chinese-American food, I especially like chicken cooked in garlic sauce or General Tso's sauce, and I also like the meat-on-a-stick things you can find at Chinese buffets. Also, I like the way Chinese buffets cook green beans.
