Thanksgiving is now less than a week away. I know my stomach can't wait, but as we approach a day off or a long weekend, let's not forget that Thanksgiving itself can potentially help pad our portfolio.

Before you run to your cupboard and search for that box of stuffing, put your feet up and read about two Thanksgiving Day staples that could fill your belly -- and potentially lift your portfolio.

Let's talk turkey
No, seriously, let's talk turkey! Agriculture company Seaboard (NYSE: SEB) is entering that bread-and-butter quarter of its year and the pun is whole-heartedly intended.

In September, Seaboard entered into an agreement to buy a 50% stake in Butterball, the most well-known brand of turkey in the U.S., after Smithfield Foods (NYSE: SFD) decided to exit the business. Seaboard has benefited recently from steadying feed costs for its livestock, and higher average selling prices for its meats, which is a win-win for its bottom line.

The company's cash flow is strong enough that the $100 million it provided as financing to Butterball is not even an issue. Don't be fooled by Seaboard's $1,940 share price -- at less than 13 times trailing earnings and showing revenue growth of 31% last quarter, you might consider gobbling up some shares.

Pass the veggies
Chances are likely that you're going to have at least one fruit or vegetable product from Dole Foods (Nasdaq: DOLE) or Fresh Del Monte Products (NYSE: FDP) on your table this Thanksgiving, but how should you choose between the two?

As an investor, what really stands out is the strong insider buying we've seen at Dole. If management is willing to put their own money into the stock, chances are they're confident about the company's long-term future.

From a financial standpoint, Dole has the higher free cash flow yield of the two, trading at a much lower forward multiple than Fresh Del Monte. We should, however, keep an eye on Dole's quarterly report, due out next week. Both Del Monte and Chiquita Brands (NYSE: CQB) suffered setbacks last week due to lower banana prices, so it may be wise to reassess Dole after that report comes out.

Have your cake
Investors can have their cake and eat it too with food suppliers. This week when you're buying your Thanksgiving supplies, keep in mind how these food producers could put some meat on your plate and some money in your wallet.
