Not really... it's very fruit heavy. We want you to eat a template meal of 1-2 palms of protein (actual chewed food), vegetables (2-3 cups that can include a fist sized serving of starchy carbs) and a fat source at every meal.
Google is the best way to search this forum. Use 'whole30 + topic' and usually the first results are forum based results.
Eggs would be fine for pre workout. Post workout is ideally lean protein and starchy carb but unless you're an elite athlete trying to get that final bit of perfected recovery, as long as you eat protein after, even if it's a bit fattier like an egg with the yolk, that's fine.
Smoothies are discouraged for all participants - from our Can I have guide:
Smoothies: We’d rather you didn’t
This is a very popular question, with a very unpopular answer. Smoothies (generally made using lots of fruit) are technically compliant on your Whole30, but we strongly recommend against it. Food that you drink sends different satiety signals to your brain than food that you chew. So when you drink your meal, your brain isn’t getting the feedback it needs to tell your body that it’s had enough of what it needs. Plus, smoothies are generally really fruit-heavy, and starting your day off with a liquid sugar-bomb sets you up for cravings, hunger, and volatile energy levels throughout the day. In summary, we’d rather you just eat the food, and skip the smoothie.
Are you doing just eggs for protein? (no fish? no legumes or dairy or other alternatives discussed as veg*n options in this article?) Egg white + sweet potato would be a better post-WO than the mushrooms, they just don't have as much protein.
Pre-WO is really important for people working out first thing in the morning, to get something in your system after fasting all night. An egg and some guac is a good option, or whatever fat choice sounds good right before a workout for you. If you're not working out first thing, and you're not feeling hungry or like you need to eat something to be able to get through your workout, you may not need the pre-WO.
Post-WO is protein & optionally some starchy vegetable. You want to have it shortly after your workout when your muscles are most receptive. This article explains more about what to have post-WO and why, but I don't think she really had any vegetarian options other than the egg white -- it's still a good summary of why you're eating what you're eating. This one is more important, really work on getting at least a little bit of protein in within a short time after your workout. A lot of people work out, have their post-WO in the car in the parking lot before they drive home, and then eat their meal a little bit later. You really don't need a lot of food for post-WO, so it shouldn't affect how much you eat for your next meal, even if you're eating pretty soon after.
I would strongly encourage you to skip the chia seed concoction you've described. If you're hungry shortly after a meal, your meal wasn't big enough. When you're eating enough, you should easily go 4-5 hours between meals. Even if you're not eating meat, you'll do best if you follow the meal template -- 1-2 palm-sized portions of protein, 1-2 thumb-sized portions of fat (or the other equivalent sizes listed in the template) and then fill the plate with vegetables. So, on a typical large dinner plate, you'll have maybe a fourth to a third of the plate with some protein, fill up the rest of the plate with vegetables, and then add a serving or two of fat.
