How exciting! Where to start? Noodle soup is a great idea, btw. The garlic is used as a garnish on various Thai dishes, including noodle soup, often alongside spring onion and coriander.
Muu or Khai Pa-lo (internet spells it lots of ways, inc muu parlow) is a delicious Thai dish that uses garlic, ginger and coriander (even better if you have the roots - if not, you could add some of the stem instead, pounded).
You can cook it with pork and/or boiled eggs and tofu. It's pretty straightforward, too. Off the top of my head, pound together a few cloves (about 10?) of garlic and coriander roots with white peppercorns, fry them together with some star anise and cinnamon stick, then add in a couple of tbsp of palm sugar, fish sauce, and cook until it caramelises slightly. You can add oyster sauce too if you have it, a tbsp or more. Throw in some stock (about a litre) and then the meat, whole chunks of ginger and bring to the boil. I don't usually fry the pork separately first but you can, then that goes in too. I let it simmer for ages, towards the end the hardboiled eggs and tofu go in, and finally garnish with coriander leaves, spring onions and pepper (preferably white). And why not some fried garlic?! I think you could add a little five spice if you don't have the star anise and cinnamon sticks. There are a variety of recipes but the one above (sorry v approximate) works well for me. Serve with white rice (although the leftovers could be served over noodles) and a green veg (ie bak choi).
Ginger is used in Thai food but not as often as some "Thai" recipes would have us believe. It's not really a good substitute for galangal, for example. If you like ginger and have time I recommend trying gaeng hangleh, a pork and peanut curry from Northern Thailand. Time-consuming though so I (used to) make double (no time now!). See if you can get kanom jeen (thin rice noodles) to serve with a green fishball or chicken curry, and a selection of sliced veg (raw white cabbage, cucumber, green beans, hardboiled egg or two).
I could go on but that's probably quite enough! Happy cooking :)
