I made this and it was delicious but I made it a much healthier way than this recipe. First off, I will NEVER use the Yoplait Light Thick and Creamy Key Lime Pie yogurt. It has all unnatural and unhealthy ingredients: Cultured Pasteurized Grade A Nonfat Milk, High Fructose Corn Syrup, Modified Corn Starch, Nonfat Milk, Kosher Gelatin, Corn Starch, Lime Juice Concentrate, Tricalcium Phosphate, Potassium Sorbate Added To Maintain Freshness, Sucralose (Splenda Brand), Natural And Artificial Flavor, Acesulfame Potassium Yellow #5, Vitamin A Acetate, Blue #1, Vitamin D3. High Frutose is NOT a healthy option of choice and is so bad for you. Plus the dyes and Sucralose another processed and unnatural ingredient is not good for your body. The Yoplait Greek Key Lime Fat Free Yogurt had double the protein and is all natural in it's ingredients in it: Cultured Pasteurized Grade A Nonfat Milk, Milk Protein Concentrate, Sugar. Contains Less Than 1% of: Corn Starch, Lime Juice, Kosher Gelatin, Lemon Juice Concentrate, Pectin, Calcium Citrate, Natural Flavor, Turmeric Extract (For Color), Vitamin A Acetate, Vitamin D3. I also used only the natural Whip topping from Trader Joe's. They have the all natural one with NO Hydrogenated Oils in it. A MUCH heart healthier option instead of the Cool Whip or any other products at the local grocers. Hydrogenated or partially hydrogenated oils are so bad for you. And I used the entire box of Lime Gelatin because the natural Greek Yogurt does not have a lot of sweet taste since it does not have the artificial sweetener, I just mixed a bit more lime juice, naturally squeezed or lime juice in a bottle as well. Letting it sit over night made it much better than just a few hours. It did not stand AS thick but enough to cut it like a pie, just not like the picture showed. Yet, it was delicious and I knew it was truly a HEALTHY dessert with protein and low in fat and all natural. I thought this was a great option to make for a HEALTHY dessert this way!
