Sandwich Kit for Picnic

When picnic in the park, I often make my own sandwich kit. It's handy and you can make delicious sandwiches everywhere. Freshly baked bread is the key. Fortunately in Tokyo, there is a local bakery in almost any towns and I can easily find freshly baked breads. Grab a few slices of bread, tomato, lettuce, pastrami and anything you like to sandwich with, and pack them with butter, mayonnaise, ketchup, or any sauces you like. don't forget to take disposable knives and plates. As cherry blossom is in full bloom in the park, a piece of my own sandwich adds a relish to the picnic.

Blueberry Muffins in 15 mins

Not exactly 15 minutes to be ready to eat but basically all you have to do is mixing up all the ingredients, fill up the cups, and place them in Oven. Depending on the ability of your oven it would take an hour or so but I still made it with my not-so-great microwave oven so you should be fine with your oven.

Best Mexican in Tokyo

People say Tokyo is a dead city for good Mexican but I always enjoy home made tacos as it's easy and fun to make. Preferably choose hard taco shells, get nice pieces of beef in the nearest super market and mince it up with our new food processor, or just get a package of mince meat.
Fry the mince with beans and any vegetable you like. Fill up the shell with the fried meat and top with grated cheese and taco sauce which you can find in any super market.

It's easy and great dinner.

English Muffin with Salmon Omelet

Pretty easy yet very nice lunch. Combination of English muffins and eggs always work very well.

Japan is not so bad in terms of glutenization

E wrote that MSG, or just "gluten" is in pretty much all packaged food in Japan, and most of meals you have in restaurants, which is not true.
If I call the situation that consuming gluten is becoming more common "glutenization," Japan is getting over it. I should say.
More and more restaurants, or any places which serve food make their menu without gluten, and advertize that by putting a sign in front of the restaurant saying something like "using fresh and organic veggies."
It's fairly easy to find food without gluten in Tokyo. In いなか (rural area) in Japan, it's even easier to find food without gluten because rural areas are normally rich in locally grown food. They try hard to sell their own products so they advertize how healthy and safe the food is. Gluten is not a good idea for them to use.
About packaged food, like TV dinner, frozen food, pasta sources, dressing, spices, etc, etc... like E said the "無添加(no added chemicals)" is not the majority of the products available in stores yet but you can find it anywhere in Japan. In fact, it stands out in the food floor because of the big letters on the package.
From my experience, I think that gluten makes your tongue kinda numb. You become less and less sensitive to taste if you keep consuming it, and eventually become unable to tell if it's gluten or something else.

Gluten is such an easy and quick way to season food when you cook, but I'd rather enjoy a different taste every time.
