Argentinian Steak Sandwich

This artisan Argentinian Steak Sandwich beautifully highlights the Teres Major cut of beef and its tender texture. Top that with char-grilled peppers and chimichurri sauce, and you have a gourmet sandwich in just over 30 minutes.  It is mouth-watering, delicious, and memorable.

Now let’s talk chimichurri sauce.  If you’ve never had it, it’s outstanding.  I would classify it as a very deep-flavored and hearty vinaigrette.  When you read the ingredients, you may think twice.  Make the sauce, and don’t look back.  This colorful uncooked, super fresh, and vibrant sauce can be used as a marinade, dipping sauce, or condiment to drizzle over meat and vegetables.

What is a Teres Major cut of beef, and why do I want to use one?

Teres major is a cut of beef from the cow’s chuck section, right below its front leg. It is about the size of a pork tenderloin and is the second most tender cut from a cow!  Yet this cut has a richer and more complex flavor than tenderloin. 

Now here’s the best news of all.  According to BBQ grill guides, the Teres Major typically retails for half the cost of filet cuts!  And…you can find these on sale from time to time if you shop at UW-Provisions or a high-quality meat market.  Next time you’re headed out for a beautiful cut of meat, look for a Teres Major.

Welcome to Foodie de Froid!

If you love real food, take pleasure in eating, and strive for mouth-watering flavor, you have come to the right place.  Here the star of the show IS the food, presenting it in a way that makes it shine.  

Tasting Experiences

We feature many appetizers and individual-sized recipes as a purposeful way to experience and share food.  

Our mouth reacts to flavors in a transitional way.  That first taste creates an exciting experience with the food’s intense flavors, textures, and visual appeal.  Yet after the first few bites, our mouths and minds adjust, and that experience deadens.  

Thus, the tasting experience!  We served 14 consecutive courses at my last tasting party.  Each was purposely selected to bring new flavors, textures, and presentations, creating surprises and wow moments throughout the night.

The Recipes

The recipes are documented with ingredients we love.  Yet my greatest hope is to have you understand why the recipes work and eventually make them into your personal version using your favorite ingredients and presentations.
