Miami's chefs, Olivia Ostrow and Ivan Barros, will compete in two cooking competition shows on the Food Network this month. Ostrow, the owner and chef of Maison Ostrow in North Bay Village, will be competing on "24 in 24: Last Chef Standing," which challenges 24 chefs to complete 24 challenges over 24 hours for a $100,000 prize. Barros will compete on "Chopped," where chefs must transform mystery basket ingredients into inventive dishes. The winner of the show will receive $10,000.
