Roasted cauliflower with salt and oil is fine, but drizzled with chimichurri it becomes something you actually look forward to eating.
This version adds toasted almonds to the classic Argentine herb sauce, which gives it body and a slight nuttiness. I make a batch of chimichurri on the weekend and use it all week on vegetables, eggs, and grilled meat. It keeps for weeks in the refrigerator.
Perfect way to enhance vegetables on a slow carb diet!

Why Cauliflower Works for Slow Carb Eating
Cauliflower definitely rose in popularity with the rise of Paleo, low-carb and slow carb diets. It’s a non-starchy vegetable with loads of fiber and very little carbohydrates, but its star status comes from its versatility.
Cauliflower is one of those low carb vegetables that can be pureed into mock mashed potatoes, baked into mock tortilla shells, shredded into cauliflower “rice” and roasted into all kinds of crusty deliciousness.
Who knew? I certainly didn’t, but now cauliflower is one of our go-to low carb vegetables. I am a particular fan of the mock mashed potatoes on busy week nights, but I love pairing roasted cauliflower with chimichurri sauce when my schedule is a bit more relaxed.
Cauliflower is sometimes referred to as one of the world’s healthiest foods. That’s an anecdotal reference of course, but there is no doubt that cauliflower is a slow carb vegetable with many nutritional benefits!
Sauces That Make Slow Carb Vegetables Better
While roasted cauliflower (or any roasted vegetable actually) with a little oil and salt is fine on its own, it pairs perfectly with a range of sauces to add variety to your meals.
Mustard sauces, tahini sauces, romesco sauces and chimichurri sauces all work to dress up roasted vegetables and make them into flavor bombs.
The recipe below involves a twist on a chimichurri sauce, with the addition of almonds. This traditional chimichurri sauce does not include the almonds.
Slow carb Romesco sauce or slow carb harissa sauce are two other flavor-packed sauces to liven up your roasted vegetables. They are all robust low carb sauces that can go with just about any other protein or vegetable on a slow-carb diet. Eggs too (of course).

The list of ingredients did not have almonds. Could you please add it with the quantity?
1/4 cup of almonds has been added to the ingredient list and a new nutritional analysis done. Thanks!
Hi Christiane, So I checked over the recipe and did the nutritional analysis using 1/4 cup of almonds. It is an older recipe of mine and I didn’t have access to nutritional calculators at that time. Hope this helps!
