When the local Harris Teeter restocked after the blizzard, the first thing I went for was chicken thighs. The second was the bunches of leeks that had been waiting patiently in the vegetable drawer of the fridge.
2 T olive oil
2.5 c leeks, chopped (about 5 small-to-medium ones)
2 t anchovy paste
2 t tomato paste
14.5 oz can of diced tomatoes, drained - reserve juice
2 pinches salt, plus more to taste
1/2 c juice from can of tomatoes
1/2 c hot water
2 small bunches thyme (maybe 5-10 stalks each)
In a flat-bottomed pan or Dutch oven, heat the olive oil over medium heat. Brown the chicken till the skin colors slightly, turning once. Remove from pan and reserve on plate. (As you can see from the pic above, I was a bit lazy with this step.)
Add the leeks, sauteing till they begin to soften.
Add the anchovy paste and tomato paste, then stir till they coat the leeks thoroughly.
Add the tomatoes. Saute for a few minutes, then add the salt, juice, and water. Return the chicken to the pot. Turn the heat to high, bring to a boil, then lower to simmering and cook till the chicken is done (25-30 minutes).
