Is that about 2 cups of cauliflower? And an entire cucumber? That seems like a lot if you're trying to get into ketosis. I count net carbs, and remain in ketosis, but I would probably not eat that much of those veggies in a day (because ketosis keeps me from needing a lot of food). Maybe salad greens instead?

When I do feel the need for quantity, I go for fatty foods as much as possible. I'll just eat an entire avocado with salt and hot sauce. Or something with a lot of butter.
