Cut the lemon and the orange into slices. I halved the orange before slicing so as to make eating it easier later.

Add all of your cut-up fruit to a pitcher. Top with 1-2 tablespoons of sugar, depending on how sweet your fruit is (and how sweet you want your sangria to be). I like it on the sweeter side, so 2 tablespoons it is for me.

Pour in 1-2 shots of Triple Sec, depending on how boozy you want your sangria to be. If you do not have Triple Sec, you could substitute with orange juice or, more traditionally, brandy.

Pour in the entire bottle of red wine. Stir to mix. Chill for several hours or overnight.

Before serving, add 1-2 cups of tonic water. I suggest starting with 1 cup, then taste it before adding more. I ended up using about 1 1/2 cups and it was strong enough for my friends who drink regularly, but not too strong for those who do not.

Serve in wine glasses, with a nice helping of boozy fruit in each glass. Garnish with some of the fresh fruit. Enjoy with good friends.
