"There is absolutely zero pasta in this recipe, just yummy caramelised cauliflower swimming in a gooey, creamy sauce loaded with cheese," she said about the recipe, according to New Idea.
In case you don't know, followers of the Keto diet must cut out all refined sugars, carbs including pasta, bread, rice and chips - which is why this "mac n cheese" recipe was a huge hit.
"I knew that if I were going to be successful on this diet, I'd have to make delicious keto versions of my favorite comfort foods," Resha said.

"It's working, because I'm down over 20 pounds (10kg) and hella inches, and continuing to melt. My energy is through the roof, clarity is my best friend, and I just get so much more done."
Understandably, people are losing it over the drool-worthy diet dish - that seems too tasty to be true.
"Made this for dinner tonight and whew child!!!!!!!! Soooooo good. That sauce was OMG!!!!!" one person wrote.
"Made it this afternoon. Fire!!!!!" another said.
"Mannnnnnn I made this this evening and it's beyond delicious." someone else wrote.
Aldi claims their Cauliflower and Cheese spin on "mac and cheese" is super easy to make.
"Instead of macaroni, boil cauliflower florets until tender, drain and mix in Greek yogurt, cheddar cheese and mozzarella until combined. That's it!"
Resha, 38, started the Keto diet earlier this year claiming it has changed her life - particularly rectifying her health problems.
"Since I was 7, I suffered from headaches, migraines, and chronic sinus issues. I'm THIRTY-EIGHT years old, and this is the first time in my LIFE I've gone more than a week WITHOUT a headache and ZERO sinus pressure," she said in an Instagram post.
"Feeling like s**t all the time often led to me being in the WORST mood of all time, irritated and annoyed because of my inability to feel good physically."
She said she didn't know sugar was the culprit and would never have known had she not stopped eating it.
"The knee pain went away. The sinus pressure went away. the headaches are gone. My joy has increased."
However, not everyone agrees with the diet which works by cutting out specific foods and food groups to put your body into a state of ketosis.

Sydney-based exercise physiologist Drew Harrisberg quit the keto diet after four months, claiming it is an unsustainable and unsafe diet.
He said while he got great overall aesthetic results, he experienced negative side effects.
"I am a diabetic and it affected my management really badly; I became insulin resistant," he told news.com.au.
"Unfortunately for people on keto, there's not enough science to back it up long term. I personally think it is a disastrous diet — yes, the short-term results are appealing because you do lose fat and you may look good and feel energetic with some symptoms improving, but it's so shortsighted."
