Vegetarian Dishes

"As a vegetarian, Trader Joe's has always offered affordable vegetarian products, which can sometimes be a challenge at other retailers," said Melissa Berry, avid Trader Joe's shopper and founder of EverydaySpokane.com.

Budget-friendly items Berry suggested include veggie burgers, chickenless strips and meatless sausages.

"Any of these items can be $5 and up at traditional grocery stores, but because Trader Joe's private labels most of these items, you can score a variety of specialty items, like burgers, for $4 or less depending on the item," she said.

Prepared Meals and Salad Kits

Not every prepared meal has to be frozen -- Trader Joe's has some affordable, delicious salad kits and other prepared meals as well.

"Let's face it, even frugal people don't want to cook all the time! Trader Joe's offers prepared meals and salad kits that are priced well, are convenient, and are a healthier alternative to take out," Berry said. "These items are usually priced at $5 or less and make a great option for a couple or single person in lieu of ordering food."

Wine

When it comes to wine, you can still be frugal while enjoying a glass of wine or a cocktail every so often. And why spend $30, $50 or $100 on a bottle of wine when you can get a decent bottle for $20 or less at Trader Joe's?

The Charles Shaw Merlot costs less than $5. Not only does it cost a fraction of what you'd find elsewhere, but it has a good reputation and is of excellent quality. This particular bottle contains notes of berries and vanilla spice. It pairs well with ahi tuna or prime rib.

Specialty Bread and Cheese

Trader Joe's has quite a few specialty items, such as artisanal bread, gourmet cheese and international foods. According to Sornoso, many of these items are reasonably priced and of high value for the price. This means you can still indulge without breaking the bank.

If you're looking for a high-end bread, consider Trader Joe's Focaccia Bread with Roasted Tomato & Parmesan. It costs $5 and pairs well with pastas and other main dishes.

Pasta and Rice

Pasta and rice are both pantry staples. They last a long time, they're versatile and they're filling. And at places like Trader Joe's, you can get them at a relatively low price.

Pick up a 2-pound bag of organic basmati rice for under $4. Cook it up with some vegetables, minced chicken and spices of your choice and you've got yourself a filling, nutritious meal -- potentially with leftovers.
