Step 1Bring water to boil in large pot over high heat. Stir in salt to blend with water. Add linguine to water, and, using a fork, stir and separate pasta strands so they don't stick together. Test pasta after 12 minutes by spearing a strand or two with a fork and running it under cold water and tasting. If still firm, cook another few minutes, testing every couple of minutes until al dente. Drain and place in large serving bowl.
Step 2Set small bowls holding garlic, chives, oregano and tomatoes alongside pasta bowl. Let everyone first add what they want to their serving bowls, then top with hot pasta. Be sure to pass salt and pepper, and finish with olive oil and cheese if desired.
