"Din din with my girls!" Rodriguez captioned the Instagram shot, which showed group sitting in front of a delicious-looking spread of barbecued skewers and an assortment of vegetables.
The father of two added in the caption, "#DaddyDinnerDate 💜💚."
The post comes three weeks after the family celebrated Ella's birthday. In heartfelt tribute to his youngest daughter, Rodriguez raved that his child is "officially a teenager" and reflected on her life thus far in honor of the special milestone.
"13. Wow. That number has meant a lot to me over the years, but today, it's even more special than ever," wrote Rodriguez, referring to the number he wore during his years playing for the New York Yankees.
"Ella - everyday you amaze me more than I could have ever imagined," the retired athlete continued. "You are smart, mature, talented, caring, and funny. I am so proud of the young woman you are becoming and so lucky and grateful to be your dad. I love you so much."
