*I used a mix of red, orange and green bell peppers and sweet red cubanelles from last summer's garden. So just use whatever peppers you enjoy.
To Oven-Roast Peppers: Slice off tops and pop out stem. Quarter peppers, clean out seeds and membranes, and place skin side-up, including tops, onto parchment paper-lined baking sheet. Bake in 375º oven for about 30-35 minutes until lightly charred on edges. Remove to cool. (*Can turn peppers over when 10 minutes are left). Slice into wide strips, stack, and slice through into desired sized-chunks keeping them good-sized so that they don't overcook later. (1/2" - 1" squares, as desired).
To Cook Rice: In small saucepan, bring 1 1/2 cups water, 1/2 tsp. kosher salt, and 1/2 Tbl. butter to a boil, stir in 3/4 cup rice, cover, lower heat to LOW, and simmer for 15 minutes. Remove from heat and let stand for 5 minutes. Remove lid, fluff with fork, re-cover until needed.
