Baked Lentil Marinara Spaghetti Squash + Sprouts Bean Sale

This Baked Lentil Marinara Spaghetti Squash is for all the pasta lovers out there wanting to cut back on the carbs without sacrificing your favorites! Using vegetables in place of pasta is a regular thing in our house. I love using spaghetti squash, zucchini, and sweet potatoes to recreate more traditional favorites like Pad Thai, Spaghetti Marinara, or Creamy Alfredo. Aside from replacing the pasta with vegetables, I love replacing ground beef with lentils. Beans and other legume, such as lentils, are full of nutrition, adding both protein and fiber to a dish, without a ton of calories or fat.

Can we say Win Win!? 

SOOO, speaking of beans and legumes, I’m teaming up with Sprouts again today, for those of you who follow along regularly, you undoubtedly know by now that this is one of my favorite places. Not favorite places for groceries, but favorite places. Period!

They have such a great selection of organic products and produce, paired with amazing weekly sales and online coupons. Last week I used a coupon on top of a sale and got a 5lb bag of organic carrots for $1.00. As in, o-n-e dollar. Crazy, right?!

And starting today, they have their “Bring on the Beans” Sale, where the following beans in their Bulk Department will be $.99/lb!

The lentils and split peas are some of my favorites, both nutritious and easy to make.

SO, my suggestion? Find the nearest Sprouts to you, and GO! Grab a large spaghetti squash, fill a bag with their green lentils from the bulk bin section, and find whatever other ingredients you need for this Baked Lentil Marinara Spaghetti Squash and make it! The tomatoes, herbs, spices, and Romano cheese give it a rich, savory flavor, while the lentils add a lovely earthiness. In the end, the dish is hearty and satisfying. Not to mention vegetarian and gluten-free, for those with special dietary needs or sensitivities.  Again, a Win Win!
