Vegetables: I cut celery obliquely into half inch wide and 2-3 inch long pieces (2 stalks) and American mini-cucumber in similar manner after removing the seeds and soft part around the seeds (1 mini-cucu). I made a wide julienne of tomato after I skinned and removed the seeds (1 medium).
I added olive oil (1/2 tbs) and butter (1 tsp) to a frying pan on medium low heat and sautéed slices of garlic (1 fat clove) and red pepper flakes (1/5 tsp or to your taste). When the garlic was fragrant, I added the celery first and sautéed for 1-2 minutes and then added the cucumber followed by the tomato. After 1 minute or so, I increased the heat to medium and added the squid rings (patted dry with a paper towel to remove any moisture) and quickly sautéed for 30 seconds or until the squid became just opaque and done. I seasoned it with salt and black pepper.
This is a very nice dish albeit it was a bit too spicy for my wife. I may have overdone the red pepper flakes and black pepper but it created a nice gentle buzzing in my mouth. The freshness and quality of the squid were quite good. Butter and garlic flavors combined with the still crunchy refreshing celery and cucumber all go well together. Squid has not been overcooked has a nice texture and taste and the tomato almost melted adding richness to the sauce and some acidity. We kept enjoying cold sake with which we started this evening.
