Grilled Lime Marinated Boneless Sirloin with Peppers, Onions & Chimichurri

Grilled Lime Marinated Boneless Sirloin with Peppers, Onions & Chimichurri

The temperature got up into the 50s this past weekend and it felt like a heatwave.  Since the days are getting longer again I decided I needed to grill. So I  fired up the grill to barbecue my  Grilled Lime Marinated Boneless Sirloin with Peppers, Onions, & Chimichurri. It hit the spot!

You could do this dish like fajitas, but we weren’t in the mood for tortillas or any sort of bread for that matter.

Boneless sirloin is a little more expensive than flank steak which many people prefer using for a dish like this.  However, unless you have plenty of time to marinate the flank steak or have an instant marinator, I find it tends to be tough and chewy. 

It definitely felt like springtime having this dish and I was excited to set it all out on my new FabSlabs cutting board. I purchased the large cutting board.

FabSlabs are naturally and permanently antibacterial boards.  I happen to spot them online and had to check them out.  I’m instantly a fan!

In fact FabSlabs are:

the WORLD’S MOST HYGIENIC CUTTING BOARD – tested extensively by NATA approved lab for E Coli, Staph, Salmonella, & Listeria. Testing showed after a short time the virus’s were unable to survive on the board. Test also showed after a 7-10 year period that there was ZERO bacteria growth.

Made from one single solid slab & free from chemicals & glue.

FabSlabs also come in a variety of shapes and sizes. Their grazing boards are ideal for the times you’re having a crew of friends over.  They come in 5 different lengths to accommodate whatever type of gathering you’re having. That’s going to be my next purchase.  

The FabSlabs individual chopping boards also come in a variety of shapes and sizes, even a heart shape, pizza board and more!

In fact they have a huge variety of shapes, sizes and even sets that you may just want to check out on your own.

I think the most unique fact about the FabSlabs that makes them Hygienic is that they come from Camphor Laurel trees. This timber is naturally and permanently antibacterial.  Besides looking super cool now, I don’t have to worry that any slices from my knives in the FabSlabs board will harbor bacteria. 

These aren’t just ideal for professionals but also home use for the everyday cook.

Now that I’ve tried mine out numerous times, I’m a HUGE fan and thrilled that I read about these and contacted FabSlabs to get my own.

Whether you make my Grilled Lime Marinated Sirloin with Peppers, Onions, & Chimichurri or your favorite dish, be sure to check out FabSlabs to insure all your food is safe in the future using FabSlabs boards. 

**If interested in purchasing from FabSlabs in the United States, please  go to: apparently the other links I’ve provided are only good for Australia deliveries.

  1. Such a simple, tasty marinade! We grilled this weekend, too….I’m so ready for spring!!

  2. This is definitely a FAVOURITE! I eat beef daily and still can’t get enough of it :-)) Your Chimichurri sauce looks fantastic too.

    • Thanks Angie. I love this dish and marinade. I especially love my new find of the FabSlabs. It’s wonderful not to have to worry about bacteria in a cutting board and they’re really pretty. 

  3. Chimichurri sauce and steak is a wonderful combo. We make a similar dish at least twice a year — so good. Your marinade looks great. Good stuff — thanks.

  4. I love this kind of meal. I checked into fab slabs, and it looks like they only ship within Australia, Tasmania, and NZ!

    • Hi Mimi,
      When i contacted them they gave me an email address to reach out to in the U.S. to order from.

      You can email and tell Seth I gave you his email address. He’s a super nice guy. I’m surprised the link didn’t take you there. I’ll be sure to post that at the bottom of my article.

  5. What fabulous flavors all rolled into one. This looks delicious!

  6. Oh my goodness! This looks absolutely fabulous. Love the charred vegetables and the chimichurri with beef – how can you go wrong. Great dish!
