Looking for new recipes for 1-year-old who needs to gain weight?

By 12 month old daughter has been losing weight off and on since she was 5 months old. We've been working with her PCM and her GI Specialist closely and haven't found a reason yet, but we have a referral to start seeing a nutritionist soon. However, we won't get to see her for a while because of scheduling. We've gotten my daughter to a point where she's not losing, but she's not gaining, either (she's 17 lbs 5 oz at 12 months-- 2nd percentile). In the past, I've simply tried to pick high calorie healthy foods by themselves and cut them up (like avocado, cheese, whole wheat bread ect). However, now that she's getting older and her tastes are more mature, I'm looking for actual RECIPES for dinner that are healthy, but high calorie. For example, pasta dishes, ect. Do you have a good recipe you can suggest? I'm running out of ideas!
