In a large pot, heat the olive oil on medium high. Then add the chopped garlic and grated ginger. Saute, reducing heat as needed for a minute or 2 to cook the garlic.
Now, add the curry paste, and stir it into the garlic and ginger. Cook for another minute.
Then add 3 cups of veggie broth and the coconut milk. Stir to combine everything. Reduce heat to low and simmer.
Next, in a medium sized bowl, whisk together the remaining cup of broth and the peanut butter. I find this makes it easier to incorporate the peanut butter.
Now, add the peanut butter and broth to the pot and whisk to combine.
Then add the soy sauce, agave and lime juice. Simmer on low for 5-10 minutes to develop the flavors. Taste and adjust seasonings. Add a pinch of salt if needed or more lime juice or agave if needed.
Right before serving, add the ramen noodles into the pot(add 9 oz if you want more broth or 12 oz if you want it more noodle heavy). Simmer them, cooking according to package directions. They usually only take a minute or two.
Serve immediately as is, or add the optional toppings, veggies or tofu or whatever you want.
