Sandwiches taste better when they're cut in triangles, preferably teeny, quarter-sized triangles. Buttered toast is at its zenith of awesomeness when sliced into three to four toast soldiers. Carrots and zucchini should be in lovely, fine julienne strips or sliced on the diagonal. I prefer my tomato diced. Shredded chicken breast tastes better than chunks.
I've always said I wasn't fussy about my food, but reading the above, well, some revisiting of that attitude is in order.
