It is vibrant tangy and loaded with crisp vegetables and tossed in a creamy sesame dressing. When my kitchen is too hot to turn on the oven this comes together in a flash and always tastes incredibly fresh.

I have always loved the nutty bite of soba noodles but my favorite ingredient has to be fresh cilantro. When I toss it in at the last moment it lifts the whole dish with a burst of green flavor. My niece now asks for “the purple noodle salad” at every family barbecue which always makes me smile.
Storage Tips
Soba noodle salad holds up very well for make ahead lunches or dinner prep. Store in an airtight container in the fridge and it stays delicious for up to three days. For best texture add fresh cucumber and cilantro just before serving as they can soften if left too long in the dressing.
Ingredient Substitutions
If you do not have tahini try natural peanut butter or sunbutter for a nut free version. Tamari swaps in for soy sauce if you want to keep it gluten free. If you cannot find black rice vinegar a gentle balsamic vinegar works well and adds a little sweetness. Add protein with pan fried tofu crisp chickpeas or if you eat seafood some chilled shrimp.
Serving Suggestions
This salad is perfect as a main for lunch or a picnic and pairs beautifully with miso soup or cold edamame. For a heartier meal top with grilled tofu or serve with a side of avocado slices for extra richness.

A Bit of Japanese Inspiration
Soba noodles come from Japan and are traditionally eaten cold during summer months. They are made from buckwheat and believed to bring health and longevity. The vibrant salad mix draws inspiration from both Japanese and Californian cuisine blending crisp vegetables with the classic noodle base.
