The love of my life prefers veggies with flavor. And this one fits the bill. I've made versions inside and out. But today the stove had to support an already crowded grill. Any onion, shallot, or garlic (!) will work, but the red is pretty.
1 red onion, halved and sliced into half moons
Two giant handfuls green beans, trimmed
1 pint small or cherry tomatoes, halved if they're large
In large skillet, slicked with olive oil, brown & soften red onion. Add green beans and season with salt and pepper. Let them get a sheen and some color. Add a few tablespoons of water. Raise the heat and mostly cover (let the steam escape) until water is gone (5-ish minutes). Add tomatoes and cook until skins are slightly roasted and juices flow. Toss, adjust seasoning and serve.
