I was vegetarian for 3 years, and always made my own Protein Shakes with Orgain Organic Protein Powder.
2 scoops of Orgain chocolate Protein powder (150 cals, 21g protein, 5g Fiber, 5g net carbs)
1Tbsp of PBFit Peanut Butter Powder (25 cals, 3g protein, 2g fiber, 2g net carbs)
2Tbsp Hemp Seeds (114 cals, 7g protein, 2g fiber, 0g net carbs)
1Tbsp ground Flax Seeds (37 cals, 1g protein, 2g fiber, 0g net carbs)
2 cups of Unsweetened Almond Milk (60 cals, 2g protein, 0g fiber, 2g net carbs)
1 medium frozen banana (105 cals, 1g protein, 3g fiber, 24g net carbs)
1 cup frozen spinach (45 cals, 6g protein, 4g fiber, 2g net carbs)
Ice and Water to desired consistency
Macros: (536 cals, 41g protein, 18g fiber, 35g net carbs)
This makes approximately 32-40 ounces depending on amount of ice and water added, so if you broke this up to 2 shakes, 268 cals, 20.5g protein, 9g fiber, 17.5g net carbs.
