Hi, I had to google "oxylates" because I didn't know what they were. I am assuming that the doctor gave you a list of what to eat and what not to eat, but if not, here's a list I found online.

Since you already have kidney issues, it's important to get your glucose levels down, as high blood sugar can cause more damage. Your numbers really aren't that bad. Mine were so much worse, just a couple months ago.
I was diagnosed type II in 2008, but I think I had it for a while before being diagnosed. I do take Metformin. The past year my glucose reading were creeping up higher than I care to admit and I knew I needed to take action. I cut out practically all carbs and started eating a lot of vegetables, mostly cooked and got back to exercising and my BS has dropped pretty good.
Your diet doesn't look bad. Here's what I would do. I would try to find a different bread. The bread I eat, when I eat bread, is called Nickles 35 lite. It might not be available in your area, but it is very thin small slices that are 35 calories each, so eating 2 slices compares to 1 slice of most other breads. You're getting less, but you still have 2 slices if you want to make a sandwich. I think Pepperige Farm has something similar.
I would try to eat only one slice at breakfast, and only eat it when you're eating your egg. The first slice of bread you're eating is turning right into glucose since you're eating it alone. Always have a protein and fat with a carb. They slow down the absorption of the carbs.
(I almost always have eggs for breakfast. I use 1 serving of egg beaters and 1 egg and scramble them. I add things to it, like sauteed mushrooms, wilted kale or spinach, onion, and a sprinkling of black beans. I buy them in a can and separate them into 1/4 c servings in little snack bags. All the snack bags go into a freezer bag and into the freezer. Each day I take out a bag, run some water over it to defrost, then keep them in the fridge, adding some to my eggs, and some to my salad or veggies at lunch.)
Instead of a tuna sandwich at lunch with 1/2 c lettuce, you could make a big salad, using other veggies besides lettuce and mix your tuna into the salad.
(I usually just have steamed vegetables for lunch. Kale, carrots, brussels sprouts, broccoli, cauliflower, or a tossed salad. We eat dinner early, so lunch is small.)
You could do the same with the tacos at dinner. Instead of using the shells, make it into a taco salad. Really, you could do one or the other, either the sandwich or the tacos.
(For dinner I usually cook a normal dinner for my husband and I, and I eat whatever I made for him, eating more vegetables and omitting whatever starch I prepared for him.)
Add as many vegetables into your diet as you can. They provide nutrients that your body needs. I would stay away from the popcorn. I know it spikes my bloodsugar. Some things I like for snacks are Edemame. They are soybeans, and I buy them shelled, frozen. I just defrost them and eat them as they are. They look like lima beans but are high in protein. I don't know if you are allowed soy products. Another thing I like is hummus. It's made from chickpeas and is good fiber. I eat it with celery sticks and red and yellow pepper strips. You could also eat Jello. They have sugar-free that isn't bad, and you can even top it with Redi-whip, that stuff that squirts out of a can. It's really low calorie.
And exercise. A walk after dinner helps. Because you are not taking meds you have to be a little more diligent, but you can do it.
Good luck to you.
