Tiffani Thiessen reveals her secrets to better sleep, nutrition — and getting her son to eat salad

Saved by the bell pepper?

It can be really difficult to get kids to eat vegetables, much less salad. But Tiffani Thiessen has a juicy secret to inspire plant pessimists to gulp down greens — put a chef or Caesar salad topped with ranch on their pizza.

“I think the first time it kind of clicked [was when] I actually put salad on my pizza,” Thiessen, 52, told The Post about getting her 10-year-old son, Holt, on board.

“And he was like, ‘Wait, you could do that?’ And I was like, ‘Of course, you can,'” she added. “He liked that sort of concept, with a lot of ranch on it. And so he’s been eating salads ever since, and that was a couple of years ago.”

Thiessen, a mother of two, loves salad, like really loves salad — and not just because she has a partnership with the packaged salad company Fresh Express.

You may remember her as a diner denizen in the ’90s, first at The Max as popular cheerleader Kelly Kapowski on “Saved by the Bell” and then at The Peach Pit as the deliciously vengeful nightclub owner Valerie Malone on “Beverly Hills, 90210.”
