In a blender, combine 1 cup of strawberries, 1 cup of blueberries, 1 cup of finely chopped spinach, and 1 grated carrot. Blend until the mixture is completely smooth.

Transfer the smoothie-like puree to a saucepan over low heat, adding 1 cup of unsweetened applesauce, 2 tablespoons of honey or maple syrup, 2 tablespoons of lemon juice, and 1 teaspoon of vanilla extract. Stir gently, heating for about 5 minutes.

Once heated, increase the temperature to medium. Evenly sprinkle 2 tablespoons of gelatin powder over the warm mixture and let it sit for 1 minute.

After waiting for a minute, stir the mixture continuously over medium heat for about 3-4 minutes until the gelatin is completely dissolved.

Remove from heat and let the mixture cool for about 5 minutes before transferring it into silicone molds or a lined baking pan.

Place the filled molds or pan in the refrigerator and allow the snacks to set for at least 2 hours.

Once firm, carefully remove the snacks from the molds or cut into squares if using a baking pan.

Store the snacks in an airtight container in the fridge for up to a week.
