Sort of Serendipity from the Common Man
“Protein Shake”
From Robert & Susan Kinaga
I needed to find alternatives for protein and energy supplements listed in cancer treatment materials and recommended from nutritionist. Commercially available “protein drinks” are labeled lactose-free, but are not dairy-free. I didn't think there was a difference until I had a most unpleasant experience at a restaurant after 3 days of drinking one of the commercial drinks.
My wife Susan developed a “Protein Shake” for me. Below is how she made them, and (as Tony the Tiger says) they are GREAAAT!
1. In a blender, she added the following to make a great shake for me even though I could not taste much of it (I'm guessing it tastes sweet)
2. Protein powder (199 cal)
3. 1.5 cups of vitamin-enriched rice milk made by Rice Dream (200 cal) 
4. One medium bananas (80 cal)
5. Plus blueberries or peaches (80 cal) --- OR - Del Monte Fruit Natural Peach Chunks (140 cal)
6. This equals approx 500 calories and 21 grams of protein
Protein powder Mediterranean 
Wellness Shake is made by Pure Trim and was special order on line, not in stores, and on the expensive side ($100 for 3 boxes of 10 servings each = $3 per serving). Many ingredients you can tell by package, but mainly vegetable pea and brown rice protein and 500mg of calcium. Key thing is no dairy, soy, whey, aspartame and sucrose. Rice Dream, fruits and juices you can find in most stores (e.g. - Whole Foods).
You may also add fruit juices instead of rice milk, but it scorched my throat due to acidity so we stayed away. Also experimented with and avoided most other fruits like citrus, even apples and others unable to tolerate.
My wife also found in the supermarket a protein drink made by Odwalla called "Super Protein". There are 8 fluid ounces (2 servings) per container = 380 calories and 18grams of protein.
I preferred Vanilla because reacted to chocolates stinging my throat. That drink is mainly soy milk, oatmeal milk, bananas and almonds.
I am very grateful for my wife finding and developing these items. She helped sustain me at most critical time during weight loss and symptoms increasing plus helped to keep me mentally in the game with the energy provided.
We hope this helps…
