A $42$-year-old woman is evaluated in the hospital on the second day of her admission for acute pancreatitis. She initially presented with severe epigastric pain, nausea, and vomiting. At the time of admission, laboratory studies showed a serum lipase of $2,400$ U/L, alanine aminotransferase (ALT) of $185$ U/L, and normal total bilirubin and alkaline phosphatase levels. Right upper quadrant ultrasound demonstrated gallstones in the gallbladder but no common bile duct dilation. She was treated with aggressive intravenous crystalloid resuscitation and opioid analgesics. Today, she reports that her abdominal pain has significantly improved and her nausea has completely resolved. She states she is feeling hungry and asks when she can eat. Her temperature is $37.4^\circ\text{C}$ ($99.3^\circ\text{F}$), blood pressure is $125/78$ mmHg, pulse is $88$/min, and respirations are $16$/min. Abdominal examination reveals mild epigastric tenderness but no guarding or rebound. Bowel sounds are present. Which of the following is the most appropriate next step in management?
