Soba Noodles with Leeks, Sweet onions and Egg

These soba noodles with leeks, sweet onions and egg are an easy and delicious vegetarian meal.

There are few groceries that set off panic mode in my brain when their supply gets dangerously low, bananas (I live with a part monkey husband), milk (omg, what do I put in my 3 cups of coffee in the morning?) and eggs.

So you might imagine my annoyance on Monday when I went for these exact three things and they were out of two out of the three.


Like, wiped out.

How a regional grocery chain can just be OUT of milk and eggs is beyond me. It’s not like there was an impending storm or anything, just “typical Monday inventory lows” according to the poor shelf stocker I sarcastically attacked when noticing there wasn’t a gallon of milk in sight.

Inventory lows? Here’s a thought, order more then.

Soba noodles with onions, leeks and hardboiled eggs

I have just about zero planning capabilities when it comes to dinner so unless it’s been made for this site or a freelance project during the day, chances are, I haven’t given even 2 seconds of thought to dinner until about 6pm when I realize all my meat is frozen and the internal debate between annoying microwave defrosting or just eating eggs in some capacity starts.

Eggs usually win.

They’re cheap, they cook quickly and most importantly, they pack a quick protein punch.

It’s why this kale and feta egg bake is also on constant rotation for easy dinners.

Sweet onion and leek soba noodles with hard boiled eggs

But meatless doesn’t have to mean boring.

This soba noodle dish, is packed with sweet sautéed onions (check out our guide for how to cut an onion like a pro) and leeks and tossed in a sweet chili soy sauce.

I love using leeks for mild onion flavor in dishes like this. They add a nice green element and count as a vegetable without that overpowering onion flavor. If you’ve grabbed a bunch from the market, make sure to check out how to properly cut leeks for a step by step guide on preparing them for cooking.

I topped the pasta with hard-boiled (although fried, poached or soft boiled would be great too!) Safest Choice Eggs. They’re pasteurized (making them worry-free for you batter-lickers out there) and a great option for your meatless meals.

Love a good bowl of noodles like this? You’ll probably also like these spicy udon noodles or my 20 minute ramen and pork stir fry.
