Eureka! The answer is 86.18g, simple because after a minute I was like skip it I will just DuckDuckGo the answer. My salad was getting warm and I was hungry. In MFP I enter 861.8g and accept it. Turns out that is 150 calories of lettuce, which seems like a lot. I check it again and realized I put the decimal in the wrong spot. With that one little mistake I had gone from eating .19 pounds of lettuce to 1.9 pounds.
Remember to make sure that what you enter into MFP is accurate because simple mistakes can make a huge impact.
