Leftovers are one of my favorite things in this world! There isn't much that beats cooking once and eating twice, right? This healthy leftover noodle recipe for Spicy Vegan Peanut Pasta Salad uses leftover spaghetti noodles and lots of fresh vegetables. I like to make this Vegan Pasta Salad the day after I make spaghetti because I inevitably end up with too many noodles.

And for years I had a hard time telling when my spaghetti noodles were actually done. I was told very early on (not sure by whom) to throw my pasta against the wall to determine if it was ready. Apparently, if it sticks, it's done. Have you ever thrown your spaghetti against the wall to test if it's ready? And, like me, did you ever wonder if this was actually a valid test or a make-work cleaning project?
Jump to:
I stopped throwing my spaghetti against the wall years ago, not because I thought it didn't work, but because it was a pain to clean up. But these days, and after 30+ years of pasta making, I can pretty much tell if my pasta is ready by its texture when I taste it. Have you heard the term al dente ? It essentially means your spaghetti is ready; it's a little tender but there's some resistance. In other words, it's not tough and it's not mushy. But I am convinced knowing if your pasta is ready is an acquired skill that takes years to master.

🍝Which type of Spaghetti to use
Then there's the question of which spaghetti noodles to use. Whole wheat takes a long time to cook and personally, I find it a bit too dense. I prefer to use "smart pasta" because it cooks faster than whole wheat but you still get 4X as much fibre than if you ate white pasta. Although it's not quite as healthy as whole wheat, you are still getting that fibre. And if you're not a fan of whole wheat, it's a good alternative.

This is a great way to use leftover noodles, which usually get thrown away at my house. I always seem to cook just the right amount of sauce but way too many noodles. Thanks for sharing!

Thanks - yes, I had the same issue!

Hi Deborah,

Mindy
Looks delicious! Do you think I could substitute soba noodles for the spaghetti?
Terri Gilson
Hi Mindy- I don’t see why you couldn’t! Really, any noodles would work-enjoy!

I have a bunch of leftover pasta that I’m trying to figure out what to do with for dinner tomorrow and can’t wait to try this recipe. Would you have any suggestions for what to eat along with it as a side?
Terri Gilson
Honestly, we eat this as a meal! But if you leave out the peanuts, it’s a great side salad with bbq pork or chicken ?
Carlos at Spoonabilities

I have leftover noodles in the fridge. Now I know what to make with them!

AWESOME.
Used leftover small bowtie noodles & finely grated the carrot, no cilantro & agave nectar instead of brown sugar - we paired it with sesame teriyaki soaked grilled salmon.
I cut up the second half of my salmon portion & mixed it in with my serving of leftover spicy peanut pasta.
YUM.
This was right up my 15 year old's alley to.
Win..win..lol
Terri Gilson
I'm so glad you liked it! Salmon sounds like a great pairing!
Monique
This salad is DIVINE! The ginger and cilantro just sing! It's also flexible and/or forgiving. I have mirin I rarely use, so I subbed some for the b. sugar. (I still had to add about 1 tsp of b. sugar to get my desired sweetness.) Didn't have enough RV, so made up the difference with WWV and lime juice. Added some cooked shrimp, a few chickpeas and avocado to the finished product. Wow! I'm keeping the dressing, pasta, and veggie mix all separate since I'm cooking for only 2 people, and this recipe made a lot of dressing. It was all so delicious. I can't say enough good things about it!
Terri Gilson
I'm so glad you loved it, Monique!
