Bring a large pot of water to a boil, salt it, add the pasta and cook until al dente. Drain and return to the pot.
While the pasta is working, in a large skillet, heat the EVOO, 1 turn of the pan, over medium-high heat. Add the beef and cook until browned, about 5 minutes. Add three-quarters of the onion, the jalapeno, garlic, chili powder, coriander and cumin; season with salt and pepper. Cook until the onion is softened, 6 to 7 minutes. Stir in the tomato paste for 1 minute, then stir in the beer.
Add the sauce to the pasta and toss. Spoon into a serving dish, top with the cheese and tent with foil to melt the cheese, about 1 minute. Top with the remaining onion, the tomatoes and lettuce- just like tacos!
