Mince the garlic and set aside.
In a small pot, boil the cashew nuts in 2 cups of water for 15 minutes.
While the cashew nuts are being boiled, Cook the udon noodles in a separate pot. Use plenty of water to cook the noodles for 4 to 45 minutes. Once the noodles are cooked, set aside ½ cup of cooked water and drain the noodles. Put the noodles in a bowl and stir in sesame oil to keep the noodles from clumping together.
After the 15 minutes are up, Drain the cashew nuts from Step 2 and blend in a mixer. Add in the garlic, olives, konbu dashi, koji salt, soy sauce, and ¼ cup of cooked water from step 3. After blending, add in the rest of the cooked water (1/2 cup of water) and blend until the mixture is creamy. Cashew sauce is ready!
Pour the cashew sauce from Step 4 to the udon noodles from Step 3 and mix well. Place the noodles on a plate and garnish with an Ice plant and mini tomatoes. Finish by topping some olives and enjoy!
