I'm only in Phase 4 for about 5 weeks, so time will tell, but here's what I know/do.
Breakfast is same as Phase 3, though I do agree that the pancreas is awake now, so having it in one sitting is not as important anymore.
Lunch, I have my usual home made soup and throw in some meat. Have my usual salad, but now I can add regular salad dressing and cheese. The amounts of fat are not real clear on the Phase 4 sheet - they just say 'at least' 1 tbsp oil. But I try not to overdo it.
Dinner, I have my usual stir-fry vegees and add meat (not all the time), and pasta or rice or some other grain I'm learning about. My Phase 4 sheet just says '1 serving' so if you look at the package of pasta, 1 serving is 2 oz dry, weighed, and it cooks up to a little less than a cup. I still use 2 tsp oil for the stir-fry, but that's it for fat at dinner. Maybe some fat-free feta on the salad, with a WF dressing.
Fruit is allowed at dinner, so I usually save that fruit for my evening snack and have yogurt as the protein snack, with fruit.
I also have a late morning and late afternoon snack, as I try to push to get my house fixed and need something, so I've been having spinach/kale smoothies with soy protein powder and WF chocolate or caramel and ice. Or, an IP bar or chips.
You can have 'unlimited' vegees, but I still find I can only eat about 2 cups with meals, but I can then have the extra spinach in my smoothies. You can have the full 7 oz meat twice a day, but you don't have to have a full 14 oz, so many times I don't. I still get plenty of protein with the smoothies.
I call the 'cheat' days 'splurge' days. I like that better.
